Overview of spherical aluminum nitride AlN particles
Spherical aluminum nitride is a kind of 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 comprehensive performance of silicon materials, it is more and more popular. Attention, widely used in the fields of large-scale integrated circuits, electronic substrates, high thermal conductivity, thermal conductivity 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 integrated electrical circuit substrates, electronic devices, optical devices, radiators, high-temperature crucibles
2. Preparation of metal and polymer matrix composite materials: especially in high-temperature sealants and electronic packaging materials with good application prospects.
3. Nano-inorganic ceramic automotive lubricants and anti-wear agents. Nano-ceramic aluminum nitride ceramic nanoparticles are used as lubricants on the metal surface of the friction pair in the engine. They are activated under the action of high temperature and extreme pressure, and are embedded with strong permeability. In the depressions and pores of the metal surface, the damaged surface is repaired and nano-ceramic coating is formed. Due to the isolation of this film, the friction is greatly reduced, and the friction between the moving parts is reduced to almost zero. Although the price of nano aluminum nitride powder is expensive, the addition amount in lubricating oil is only two ten thousandths, and the cost performance is very high.
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 good thermal conductivity, good electrical insulation, wide electrical insulation temperature, low consistency and good construction performance. It is widely used in the gap between the CPU and the heat sink, high-power transistors, thyristor components, diodes, and the heat transfer medium at the thin joints 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 matching performance and are easy to disperse in the rubber. It can greatly improve the thermal conductivity of silicone rubber without affecting the mechanical properties of the rubber. Like oxide, the viscosity rises very quickly during the process of adding, adding a small amount, widely used in military, aviation and information engineering.
6. Other application areas: Nano-aluminum nitride is used in smelting non-ferrous metals and semiconductor gallium arsenide crucibles, evaporation boats, thermocouple protection tubes, high-temperature insulation parts, microwave dielectric ceramic materials, high-temperature corrosion-resistant structures, etc. Microwave transparency Aluminum nitride ceramic products, currently used in PI resin, thermal insulation mica tape, thermal grease, insulating paint, thermal oil, etc.
