Product performance and application of aluminum nitride AlN powder

Overview of spherical aluminum nitride AlN particles

The aluminum nitride powder (CAS 24304-00-5) sold by our company has high purity, ultra-fine particle size, and high surface activity. The powder is treated by surface cloth, with extremely low oxygen content (<0.1%), insulation and heat conduction. The performance effect is obvious.

How is it produced? Thermal spraying process: Aluminum nitride powder can be thermally sprayed to form electrical insulation and thermal conductivity coatings. Chemical/Physical Vapor Deposition (CVD/PVD): Deposition of aluminum nitride coating by CVD or PVD to provide electrical insulation and thermal conductivity coating.

Spherical aluminum nitride is a high thermal conductivity material of inorganic powder. Because of its high thermal conductivity, good insulation, low dielectric constant, as well as the considerable expansion coefficient and excellent overall performance of silicon materials, it is more and more popular. Attention, widely used in large-scale integrated circuits, electronic substrates, high thermal conductivity, thermal conductive inorganic fillers, high-performance structural ceramics and other fields.

With the advent of the 5G era, various electronic devices are becoming more integrated and more powerful. In order to improve the heat dissipation performance of various packaging resins used in the electronic field, the best way is to add inorganic insulating fillers with high thermal conductivity to the materials. Aluminum nitride is one of the best choices. In order to increase the filling amount, the powder is required to be dense and spherical, with a particle size ranging from tens of microns to hundreds of microns, to ensure that the size and particle size of the composite can achieve high filling and good fluidity.

Application of spherical aluminum nitride AlN particles

1. Manufacturing of high-performance ceramic devices: manufacturing of integrated circuit substrates, electronic devices, optical devices, radiators, and high-temperature crucibles

2. Preparation of metal and polymer-based composite materials: especially in high temperature sealants and electronic packaging materials, it has a good application prospect.

3. Nano-inorganic ceramic automotive lubricants and antiwear agents. Nano-ceramic aluminum nitride ceramic nanoparticles are used as a lubricant for the metal surface of the engine friction pair. They are activated under the action of high temperature and extreme pressure, and have strong permeability. In the depressions and pores of the metal surface, the damaged surface is repaired to form a nano-ceramic coating. Due to the isolation of the film, the friction force is greatly reduced, and the friction force between the moving parts is reduced to almost zero. Although nano-aluminum nitride powder is expensive, the addition amount in lubricating oil is only two-tenths, which is very cost-effective.

4. Used in the manufacture of thermally conductive silica gel and thermally conductive epoxy resin. Ultra-high thermal conductivity nano aluminum nitride composite silica gel has the characteristics of good thermal conductivity, good electrical insulation, wide electrical insulation temperature, low consistency and good construction performance. Widely used in the gap between the CPU and the heat transfer medium at the heat sink, high-power transistor, thyristor element, diode, and the thin joint in contact with the substrate.

5. The application of aluminum nitride powder in high thermal conductivity silicone rubber: the bottom aluminum and silicon nitride have good coordination performance and are easy to disperse in the rubber. Without affecting the mechanical properties of rubber, the thermal conductivity of silicone rubber can be greatly improved. Like oxides, the viscosity rises quickly during the addition process, and the addition amount is small. It is widely used in military, aviation and information engineering.

6. Other application fields: Nano-aluminum nitride is used for smelting non-ferrous metals and semiconductor gallium arsenide crucibles, evaporation boats, thermocouple protection tubes, high-temperature insulating parts, microwave dielectric ceramic materials, high-temperature corrosion-resistant structures, microwave transparent aluminum nitride Ceramic products are currently used for PI resin, thermal insulation mica tape, thermal grease, insulating paint, thermal oil, etc.
