We will continue to develop and produce more energy-saving Boehmite, poly aluminium chloride in paper industry, pseudoboehmite alumina powder, so as to make greater contribution to reduce the cost of users and protect the ecological environment. Our quality inspection department will pay attention to the quality of products in the whole production process and monitor the whole process. We make preparations before production and reasonably arrange the production operation plan. The integrity-based, firm belief and strict, ruthless and practical corporate style are the cornerstones of our company's continuous development and transcendence. We are willing to work together with our customers and partners to seize the highest point in the market and create a better future!

Aluminum nitride is a kind of advanced thermal conductivity material, not only has the characteristics of ceramic insulation, low thermal expansion, but also has the thermal conductivity of metal copper aluminum, its thermal conductivity is 7~ 10 times of alumina, mechanical properties and alumina ceramics, but also has similar thermal expansion coefficient with silicon.

Aluminum nitride powder is mainly used to make power semiconductor chip support and heat dissipation substrate, and is widely used in communication base station, automobile, high-speed rail and power grid, consumer electronics, national defense and other fields.

Aluminum nitride has high purity, low oxygen content, high sintering activity and activitySharp size distribution 

Aluminum nitride has high thermal conductivity and insulation, adding it to resins or plastics can significantly improve the resin or

Thermal conductivity of plastics.So it is widely used in thermal conductive filler
