Spherical Quartz Powder Properties And Applications

/ / no Comments

Spherical quartz powder It is made by using a carefully selected, irregular-angled, silicon micropowder for the raw material. Then, it is shaped into a round shape with flame melting to get a silica powder that has a low stress, good fluidity, small surface area and a low specific surface.

Spherical Quartz Powder Properties

Spherical Quartz Powder has excellent properties including a smooth surface and a large specific surface area. It also has chemistry that is stable, as well as a high degree of hardness.
Firstly, the spherical granules are well-mixed with resin and form a thin film. The resin content is low, while the quartz powder amount is high. This can result in a mass percentage of up to 90.5%. The more quartz powder that is added to the mold, the less thermal conductivity it has and the less thermal expansion coefficient. The performance of electronic components is improved when they are closer to monocrystalline silicon's thermal expansion coefficient.

Second, the stress on the spherical quart powder is only 60% that of an angular powder. And the plastic molding material made of spherical quart powder has the least concentration of stress and the greatest strength.

Finaly, the spherical shaped powder has a smooth, non-abrasive surface with a low coefficient of friction. It also wears the mold less, which increases its service life by more than ten times.

Applications for Spherical quartz powder

It has many applications. However, its main market is electronic packaging. Electronic packaging is an important industry that supports integrated circuits. The packaging requirements are increasing as integrated circuits get larger and larger.

Microelectronic packaging requires a high level of moisture resistance, low radiation, resistance to dip-soldering and reflow-soldering, as well as good sealing performance. Spherical Quartz Powder is used as an important EMC material. This powder must meet specific packaging specifications, and also have a high level of purity, low alpha radiation, and spherical particle shape.

Quartz powder, which is mainly used for electronic packaging, can also be used for high-quality cosmetics, precision ceramics at high levels of quality, precision grinding optical devices, electronic components, as well fillers and special paints.

The Preparation Methods of Spherical Quartz Powder

/ / no Comments

Spherical quartz powder Has excellent properties including smooth surface, large surface area specific, high hardness, stable chemical properties. Spherical Powder has good fluidity, and it is mixed evenly with resin to create a film. The amount added of resin is low, while the filling of quartz powders is high.
The lower the thermal conductivity and the smaller thermal expansion coefficient the molding compound, the higher the amount of quartz powder. The performance of the electronic component produced is better if the thermal expansion coefficient of silicon monocrystalline is close to that of the molding compound.

It is made by purifying and ultra-finely grinding natural quartz stone, and then passing it through a high temperature field. This causes its phase, shape and crystal to change instantly, from solid to molten to solid, and from crystalline to amorphous. Its preparation methods are currently mainly high-temperature Plasma melting, high-temperature Melting Injection Method and Gas Combustion Flame Method.

High Temperature plasma Melting
The high temperature plasma melting method sprays quartz powder into the plasma flame using high-temperature gases generated by AC/DC arc plasma. The powder is heated to melt and then instantly vaporized. It is then quenched and collected with a cloth bag and a cyclone. This produces spherical silica powder. It is characterized as a high heating temperature which can achieve a temperature field more than five times higher than chemical burning (above 3000K). A high temperature, high heat, and a high active atmosphere cause the chemical reaction to proceed quickly. This leads to the rapid formation high temperature phase compounds, which are difficult for liquid phase chemistry to synthesize. Such as nitrides carbides, borides etc. After rapid cooling, particles that have left the plasma will not grow.

The technology of plasma is extremely difficult. The magnetic and electric properties of plasma have an impact on the plasma temperature field. The temperature field has a small and concentrated size. Second, the generation of plasma energy is achieved by the current flowing through the ionized medium. A plasma that is too diluted will interfere with the current, and the effect will be lost. It is hard to control how fast the product spheriodizes.

High Temperature Melt Injection
The high-temperature injection method involves melting the material to a liquid by putting it in a hot field. When the melt comes out of the ejector it is sprayed high-pressured air, which breaks up the melt and disperses it into mist. When the droplets cool down, they shrink back into smooth spheres. High temperature melt spraying allows for the most amorphous, spheroidal rate. The key technologies of viscous quartz melting atomization in furnaces, high temperature materials for the quartz, and the prevention of secondary pollutants have yet to be developed. This makes it difficult to make high-purity spherical powder.

Gas Combustion Flame method
Gas combustion flames are produced by using acetylene and hydrogen in conjunction with natural gas or other fuels as raw materials. Air or oxygen is used to support the flame. The airflow is used to transport the angular quartz into the flame. As the angular particles pass through the flame field of high temperature, they are first melted to amorphous powder. It shrinks immediately into spherical powder when it exits the high temperature field. The cyclone then collects the final product. Thermodynamics, gas dynamics and particle hydrodynamics are all involved in this method. The temperature field in plasma high-temperature fires is much lower and there are also fewer factors that influence it. It does not involve electromagnetic theory or the flow ions in an electromagnetic field. The movement problem makes it easier to manage various conditions. Equipment manufacturing is simplified, industrialization is easy, and development prospects are better.

The Main Preparation Method of Spherical Quartz Powder

/ / no Comments

What is spherical Quartz Powder?

After being purified from quartz stone, sphere quartz powder is pulverized and ultrafinely pulverized. The powder then goes through a high temperature field so that its phase form, crystal form and shape instantly change, going from solid to molten and then to solid to solid. Amorphous powder is made from irregular angular particles and transformed into regular spherical grains.

The main preparation method for spherical powder quartz is

1. Flame melting is used primarily to mass produce spheroidized quartz dust. This technology has a key feature: the heating device must have a stable temperature field, a temperature range that can be adjusted easily, and there must be no secondary pollution to quartz powder. The ball-forming principle is that the high-temperature fire spray gun produces a high temperature flame between 1600 and 2000. The powder enters the high heat flame zone and its angular surface absorbs heat. This heat is then transferred to the powder's interior, where it is completely molten. The action of surface tension means that objects tend to be stable. Spherical is the best state for forming a ball.


2. The local thermodynamic equilibrium (or thermal plasma) is another name for this plasma. The main characteristic of thermal plasma is the fact that the plasma's electron temperature, ion temperature and gas temperature are all almost identical. The thermal plasmas are arc plasma, high frequency and induction plasma.


The high-frequency plasmafusion method is used for the preparation of spherical quartz. This method has a moderate range, stable control, high output, and can achieve a high rate of spheroidization, so it's a better production method. The principle and procedure are similar to that of flame melting. This mainly transforms the high-temperature heat source into an plasma generator.


The working gas is compressed gas. The volume of the working gases is 10m3/h. The high-frequency generator generates heat by generating high-temperature gas at 4000-7000. The silica is carried from the top of the plasma reactor furnace to the arc region by the feeder. After melting and gasifying, the powder is then transported through the feeder. The powder is quenched using a special quencher, then collected by gravity and bag dust (nanoscale). In a matter of 1s-2s the spherical and nanoscale SiO2 can be obtained.


3. Chemical synthesis

To obtain silica sol, heat the silica emulsion with ammonia or ammonium bicarbonate. The gel is then treated with acid to produce hydrated spherical silica. This product has a low uranium level, which is a characteristic. However, it is also easy to agglomerate.

Reasons for Spheroidization of Spherical Quartz Powder

/ / no Comments

What is spherical Quartz Powder?

Spherical Quartz Powder, also known by spherical Silica powder, is an amorphous powder of quartz that is spherical in form and contains silicon dioxide as its main component.

Spherical quartz is used primarily for copper clad laminates, epoxy molding compound, fillers in large scale integrated circuit packaging. However, it also has applications across high-tech areas such as aerospace, fine chemicals, and daily cosmetics.

Why is Quartz Powder Spheroidized

1. The ball has a small surface area, isotropy, fluidity, and filling quantity. It can have a mass ratio of 90.5%. The filling speed of silica micropowder can be increased.


The filling rate for silicon micropowder is higher, but the plastic sealing compound's thermal expansion coefficient is lower. The thermal conductivity of the plastic sealing material is also lower, so it is more similar to monocrystalline silicon. This will improve the performance of electronic components.


2. The strength and stress concentration of the plastic sealing compound made from spherical dust is the lowest. The plastic sealing compound made of angular powder has a stress concentration equal to 1, but the stress from the spherical is only 0.6. When the spherical dust plastic sealing compound is used to encapsulate the integrated circuit chips, the yield is High. This makes it difficult to cause mechanical damage during transport and installation.


3. The friction coefficient for spherical powders is low, the wear on molds is small and the mold's service life is very long. The service life of the mold is doubled when compared to angular powder. The cost of plastic sealing compound packaging molds is high. It is therefore necessary for some to be imported.


4. Silicon micropowder has the ability to strengthen epoxy resin. Spherical powder can also enhance this effect.
