Nano aluminum nitride belongs to the diamond-like category.Nitride, can be stable toAt 2200°C, it exhibits high room-temperature strength, and the strength decreases slowly as the temperature rises. Nano-aluminum nitride powder has good thermal conductivity, a low coefficient of thermal expansion, and a theoretical thermal conductivity value of 3.40 W/mK, similar to copper, yet highly insulating, with a resistivity of 10¹⁵It can withstand temperatures up to 1400°C, significantly enhancing the thermal conductivity of plastics and silicone rubber. It is an excellent thermal shock-resistant material with strong resistance to molten metal erosion, making it an ideal crucible material for melting pure iron, aluminum, or aluminum alloys. Nano aluminum nitride exhibits excellent electrical insulation and good dielectric properties. It also has favorable injection molding performance. When used in composite materials, it demonstrates good compatibility with semiconductor silicon and excellent interfacial compatibility, thereby improving the mechanical properties and thermal dielectric performance of the composites.

2. Thermally Conductive Silicone and Thermally Conductive Epoxy Resin: Using our company's nano-aluminum nitride, we have produced ultra-high thermal conductivity silicone, which exhibits excellent thermal conductivity, superior electrical insulation, a wide range of electrical insulation properties, and a broad operating temperature range (working temperature).80-250℃), low viscosity, and good workability. The product has reached or surpassed imported products, and because it can replace similar imported products, it is widely used as a heat transfer medium for electronic devices, improving work efficiency. For example,Between the CPU and heat sink, high-power transistors, thyristor components, diodes, and the narrow gaps where they contact the substrate, a heat transfer medium is used. Nano thermal paste fills the gaps between ICs or transistors and heat sinks, increasing their contact area to achieve better heat dissipation.

3nm Lubricant and Anti-Wear Additive: The modified nano-aluminum nitride ceramic particles added to nano-ceramic engine oil act on the metal surfaces of friction pairs inside the engine along with the lubricant. Under the influence of high temperature and extreme pressure, these particles are activated and firmly penetrate into the surface indentations and micropores of the metal, repairing damaged surfaces and forming a nano-ceramic protective film. Due to the isolating effect of this film, the friction generated by the relative motion between components only acts on this protective layer. The nano-ceramic particles, functioning like tiny ball bearings, partially transform the traditional sliding friction between friction pairs into rolling friction, thereby significantly reducing friction. This reduces the friction between moving components to nearly zero, providing exceptional anti-wear protection for the engine. By improving lubrication, the friction coefficient can be reduced.80%Above, to enhance wear resistance.350%Above, reduce wear.80%The above can extend the lifespan of mechanical parts.More than three times, reduce downtime, lower maintenance costs, extend the overhaul period by more than double, and save energy.10%-30%, improve the output power of the equipment.20%-40%Its addition amount is only 0.02% to 0.1%.
