Technical Parameters

Product Performance:

1、Nano aluminum nitride and ultrafine aluminum nitride powder are prepared using a variable current laser ion beam gas-phase method, featuring high purity, small particle size, large specific surface area, and high surface activity. The surface-modified powder does not undergo hydrolysis reactions and has an extremely low oxygen content (<0.1%), the insulating and thermal conductivity effects are very significant. When used in polymer resins, it does not noticeably increase viscosity and is currently the **high thermal conductivity insulating filler**. Nano aluminum nitride belongs to the diamond-like nitride category, **stable up to 2200°C**, with high room-temperature strength that decreases slowly as temperature rises. Nano aluminum nitride powder exhibits excellent thermal conductivity, a low thermal expansion coefficient, and a theoretical thermal conductivity value of 320 W/mK, comparable to copper. At the same time, it is highly insulating, with a resistivity above 10^15 Ω·cm, and can withstand temperatures up to 1400°C. It can significantly enhance the thermal conductivity of plastics and silicone rubber, making it an excellent thermal shock-resistant material. It also has strong resistance to molten metal corrosion, making it an ideal crucible material for melting pure iron, aluminum, or aluminum alloys. Nano aluminum nitride possesses excellent electrical insulation and good dielectric properties. It also has good injection molding performance. When used in composite materials, it matches well with semiconductor silicon and exhibits good interfacial compatibility, thereby improving the mechanical, thermal, and dielectric properties of the composite.

1、Application direction:

1. Manufacturing integrated circuit substrates, electronic devices, optical devices, heat sinks, and high-temperature crucibles for preparing metal-based and polymer-based composite materials, particularly in high-temperature sealants and electronic packaging materials to enhance heat dissipation performance and strength characteristics. It has excellent application prospects and can replace currently imported micron-sized aluminum nitride.

2. Thermally Conductive Silicone and Thermally Conductive Epoxy Resin: The ultra-high thermal conductive silicone produced using our company's nano-aluminum nitride exhibits excellent thermal conductivity, superior electrical insulation, a wide range of electrical insulation and operating temperatures (working temperature 80-250°C), low consistency, and good workability. The product has reached or surpassed imported counterparts, making it a viable substitute for similar imported products. It is widely used as a heat transfer medium for electronic devices to improve operational efficiency. For example, it serves as a heat transfer medium in gaps between CPUs and heat sinks, high-power transistors, thyristors, diodes, and fine gaps in contact with substrates. Nano thermal paste fills the gaps between ICs or transistors and heat sinks, increasing their contact area to achieve better heat dissipation.

3. Nano Lubricating Oil and Anti-Wear Additives: The modified nano-aluminum nitride ceramic particles added to nano-ceramic engine oil act on the friction pair metal surfaces inside the engine through the lubricating oil. Under the influence of high temperature and extreme pressure, these particles are activated and firmly embed 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 mechanical components only acts on this protective layer. The nano-ceramic particles, functioning like tiny ball bearings, partially convert the traditional sliding friction between friction pairs into rolling friction, thereby significantly reducing friction and bringing the friction between moving components to nearly zero. This provides exceptional anti-wear protection for the engine. By improving lubrication, it can reduce the friction coefficient by over 80%, enhance anti-wear capability by more than 350%, decrease wear by over 80%, extend the lifespan of mechanical parts by more than three times, reduce downtime, lower maintenance costs, double the overhaul interval, save energy by 10%-30%, and increase equipment output power by 20%-40%. The addition amount is only 0.02% to 0.1%.

4. Application in High Thermal Conductivity Plastics: The modified nano-aluminum nitride powder can significantly enhance the thermal conductivity of plastics. Experimental results show that adding 1-3% of this product to plastics can increase the thermal conductivity from the original 0.3 to 3, achieving a more than tenfold improvement. It is currently mainly used in PVC plastics, polyurethane plastics, PA plastics, functional plastics, and others.

5. Other Application Fields: Nano aluminum nitride can be used in crucibles for smelting non-ferrous metals and semiconductor materials such as gallium arsenide, evaporation boats, protective tubes for thermocouples, high-temperature insulating components, microwave dielectric materials, high-temperature and corrosion-resistant structural ceramics, and transparent aluminum nitride microwave ceramic products.
