Property of aluminum nitride Powder

Aluminum nitride has the chemical formula AlN. It belongs to the hexagonal crystal system and has a wurtzite structure.

Aluminum nitride has a stable temperature up to 2200. It is strong at room temperatures and loses strength slowly with increasing temperature. Aluminum nitride is a thermal shock resistant material with good thermal conductivity. AlN Powder is a good crucible material because it has a high resistance to corrosion from molten metal. Aluminum nitride has good dielectric and electrical properties.


Use of aluminum nitride:

Aluminum nitride has many uses in optoelectronics. It is used as a dielectric in optical storage interfaces and electronic substrates, as a chip carrier that has high thermal conductivity for military purposes, and also as a chip carrier.

1. Aluminum nitride powder AlN has a high purity and activity. It is used as the main raw material to produce high thermal conductivity aluminium nitride ceramic substrat.

2. Aluminum nitride is a ceramic substrate with high thermal conductivity. It has a low expansion coefficient and high strength. It is an excellent large-scale heat dissipation and packaging substrate.

Aluminum nitride has a higher hardness than traditional alumina. However, due to the high price, it is only suitable for parts that are severely worn.

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. It can also be used to make microwave dielectric materials, transparent aluminum nitride microwave products.
