/ / no Comments

Aluminum nitride AlN Ceramics Aluminum nitride ceramic material is a refractory, composite ceramic material that has a hexagonal wurtzite. Pure aluminum Nitride is blue-white. Aluminum nitride ceramics, on the other hand, are typically gray or white.
Aluminum nitride AlN melts at 2800°C and is stable at higher temperatures in an inert environment. It has excellent thermal conductivity and electrical insulation properties. Additionally, it has low dielectric constant and loss. This combination makes it a valuable advanced material for many applications, including optics and lighting, electronics, renewable energy, and other electronic devices.

Aluminum nitride structure
Aluminum nitride AlN is a covalent bonding substance with a hexagonal crystal structure. The most common methods of preparing aluminum Nitride include direct nitridation (carbothermal reduction), high-energy ball milling and high-temperature self propagating synthesis. Chemical vapor deposition is another popular method.

The preparation method for aluminum nitride clays
Aluminum nitride clays can be prepared in the same way as other ceramic materials. There are three main preparation methods: powder synthesis; molding; and sintering.
As the raw material, aluminum nitride is used to make the final ceramic product. Its purity, size, particles, oxygen content, and other impurities have a significant impact on the thermal conductivity, subsequent drying, and the forming of the final product. It is the outstanding performance of the final product. cornerstone. There are several ways to make aluminum nitride, including direct nitridation or carbothermic reduction, self propagating high-temperature synthesizing, chemical vapor deposition, and self-propagating.

Molding process for aluminum nitride dust
There are many ways to mold aluminum nitride for powder. These include traditional molding processes like molding, hot pressing and isostatic press. All of them are possible. All are applicable due to the high hydrophilicity aluminum nitride granules. To reduce the risk of aluminum oxide oxidation, avoid contact with water while molding. Although hot pressing and isostatic presses are capable of preparing high-performance bulk aluminium nitride materials, their high production costs and inefficientness cannot be met by the rising demand for aluminum substrates for electronics. This problem was solved by adopting the casting method to create aluminum nitride clay substrates. The aluminum nitride clays used in electronics manufacturing are also made using the tape casting process.

Aluminum Nitride Ceramics
Aluminum nitride ceramics are also used extensively as a substrate, electronic film material and as a coating for crucible or other refractory material. Aluminum nitride can also be used as a container to vacuum evaporation and the smelting metals.
Its numerous excellent properties make aluminum nitride a versatile material. It is a piezoelectric film and has been widely used. As the market develops, the applications of aluminum nitride-ceramic materials will expand. This is becoming more common.

What is Nano Aluminum Nitride Powder?

/ / no Comments

What is Aluminum Nitride Pulver? Aluminum nitride, also known as AlN, is an inorganic metal non-metallic material that is similar to diamond. It has a high thermal conductivity and low thermal expansion coefficient and is excellent for thermal shock. It is resistant to corrosion in molten metal and makes a great crucible for casting aluminum, aluminum or any other alloy. Aluminum nitride has excellent potential applications in the area of electrical component manufacturing. The large-scale production of integrated circuits is a popular application for ultrafine aluminum Nitride powder.

What is Nano Aluminum Nickel Powder?
Aerosol ablation produces nano aluminum nitride, also known as AlN. It is extremely pure, has a small particle size, and exhibits high surface activity. The powder obtained by surface modification is not subject to hydrolysis, and it has very low oxygen levels. It is easy to see the impact of insulation and thermal conductivity (0.01%). The viscosity increases are not evident when it is used in polymer compounds. It is currently the best high-thermal conductivity insulating filler. A nano-aluminum-nitride is a nitride with diamond-like properties. It can be stable to 2200 at room temperatures and decreases with increasing temperature. It is resistant to heat shock and anti-melting. This makes it an excellent crucible material for casting pure aluminum, aluminum alloy, or pure iron. Nano-aluminum is also compatible with semiconductor silicon, making it ideal for compounding.
Application of Nano-Aluminium Nitride Powder
1. Nano lubricating and anti-wear oil: The nano ceramic oil contains modified nano aluminum Nitride ceramic particles. These ceramic particles act on the friction pairs inside the engine. To repair damaged surfaces, it is embedded in the dents and micropores of the metal to form a nanoceramic protective coating. Because of the film's isolation, friction created by relative movement between the parts does not act on it. The nano-ceramic particles (like small balls) transform some of the friction between friction pairs into rolling friction. This reduces friction and reduces friction between moving parts. It also protects the engine from wear. You can reduce the friction coefficient by up to 80% and increase the anti-wear performance by more then 350% by improving your lubrication. You can reduce wear and tear by up to 80%, increase life expectancy by more the three-fold, decrease downtime, improve maintenance costs, prolong overhaul period by more over twice, reduce downtime by 10%-30%, increase energy efficiency by 20%-40%, and increase your equipment's output power by 20%-40%. It takes only two thousandths to one millionths.
2. High thermal conductivity plastics can be used with modified nano aluminum Nitride powder. This can dramatically increase the thermal conductivity. Add 10-30% of the experiment product to the plastic and the plastic's thermal conductivity will increase from 0.3 to 3. The plastic's thermal efficiency can also be increased. This material is used primarily in PVC plastics and polyurethane plastics. ;
3. Other fields of application: Nano-aluminum is also used in crucibles that are used for smelting nonferrous metals and semiconductors GaAs, evaporation tubes, thermocouple protection tube, thermocouple protection tubes and high-temperature insulation parts.

What are Aluminum Nitride Characteristics?

/ / no Comments

History of Aluminium Nitride Aluminum nitride A type of ceramic material, has a very high comprehensive performance and can be traced back over 100 years. F. Birgeler discovered it in 1862. A. Gutter synthesized it by J.W. The first use of mallets was in 1877. However, it didn't find any practical application over the next 100 years. It was used only as a fertilizer, but as a nitrogen fixing agent.

Aluminum nitride can be sintered because it is a covalent chemical with a low self–diffusion coefficient. Aluminum nitride ceramics first became commercially viable in the 1950s. They were used as refractory materials during the smelting process of aluminum alloys, pure iron, and aluminum. The technology used to prepare aluminum nitride is becoming more sophisticated and the application range has expanded. This has been evident since the 1970s. The 21st century has seen rapid developments in microelectronics technology. Electronic machine and electronic parts are moving towards miniaturization and light-duty integration. They also have a development direction such as high reliability, high power output, more complex heat dissipation devices to the substrate and packaging materials that are more requested, which will further encourage the growth of the aluminum industry.

Aluminum Nitride Characteristics
Structure
Aluminum nitride, also known as AlN, is a hexagonal wurtzite-covalent bond compound that has the following lattice parameters: A =3.114, and C =4.986. Pure aluminum Nitride is a blue-white semiconductor material with a wide bandgap of iii to vwide.



Performance
Aluminum nitride is an aluminum nitride that has superior performance to alumina.

Aluminium Nitride Thermal Conductivity Method
One of the many important properties of aluminum Nitride is its high thermal conductivity. There has been a lot of research into the thermal conductivity mechanism in aluminum nitride. A theoretical model that is almost perfect has been developed. Heat transfer through lattice (or lattice vibration) is the key mechanism. It can be done by either lattice waves or thermal waves. Quantum mechanics shows that lattice wave can be considered the motion of a particle (the phonon), according to quantum mechanics. Wave-particle duality can also be found in thermal waves. Thermal phonons transmit heat through mutual restriction of and coordination among vibrations between structural elements (atoms or ions) If the crystal has a non-elastic structure, the heat can flow freely from one end to the other without interference or scattering. The thermal conductivity can even reach very high levels. The main controls on thermal conductivity are crystal defects and the phonon scattering.

AlN has a theoretical thermal conductivity value of 320W*m-1*K-1. However, the thermal conductivity actually measured by AlN is 200W*m-1*k-1 because of impurities and defects. This is because the crystal has a variety of structural elements that cannot be distributed uniformly and the current-carrying, phonons are constantly scattered.

Use of Aluminium Niitride
The majority of current research is focused on developing a semiconductor-based light emitting device (gallium nutride or alloy aluminum gallium nanonitride) that can operate in ultraviolet light with a wavelength up to 250 nanometers. An inefficient diode can emit light up to 210nm [1] as reported in May 2006. An aluminum nitride single crystal has an energy difference of 6.2eV, measured by the reflection of UV rays. In theory, this energy gap allows waves with wavelengths of around 200 nanometers to pass through. However, commercial implementation presents many difficulties. Aluminum nitride has many uses in optoelectronics. This includes as dielectric layers for optical storage interfaces and electronic substrates. Also, it is used as chip carriers with high thermal conductivity for military purposes.
The properties of aluminum Nitride's piezoelectric effects make epitaxial stretching of aluminum Nitride crystals a good choice for surface acoustic-wave detectors. The detectors can be placed on silicon wafers. It is difficult to produce thin films reliably in these locations.
Aluminum nitride clays can be used for heat exchanger materials and high-temperature structural parts.
