The high-purity and ultra-fine Al2O3 product is developed by Nanjing Fu Hao Crystal Materials Technology Co., Ltd. together with Jiangsu University.
The products of our company are made through special process. Under the clean working environment condition, firstly we refine the common aluminum ingots with 99% purity into the high purity ones through the physical method; then calcine into the α-Al2O3 powder with high temperature by the means of atomization processing. Finally, the powder after calcining could generate the ultra-fine powder through the air classification.

The high-purity alumina raw materials produced by our company have been tested by Shanghai Silicate Research Institution and the relevant authorities. And the purity is above 99.999%，the granularity can reach to the nanometer level. All guests are welcome to visit us for further negotiation.

Application and purpose：
Lithium battery diaphragm ceramic coating, thermal interface materials, pouring sealant of thermal conductivity, thermal conductive plastics, thermal silicone grease, thermal conductivity of clay and flexible CLL etc..
