5N Al2O3 powder, 99.999% Al2O3, 5N aluminum oxide, High purity alumina powder

5N Al2O3 powder, 99.999% Al2O3, 5N aluminum oxide, High purity alumina powder
Product name : 5N Al2O3 powder, 99.999% Al2O3, 5N aluminum oxide, High purity alumina powder
Item : 5N Al2O3, 99.999% Al2O3, 5N aluminum oxide, High p
Details :
The laser class superhigh purity alumina powder (RTM-5) purity is over 99.999%, which was inspected by the authorized organization “China Academy for Building Materials Industry - Designing Institute”. People's Liberation Army General Armament Department approved to use 5N product of our company as standard to make the national military standard GJB3933-2000 in 2000. The product has a high purity which the particle size distribution and particle activity are ideal. The crystal manufactured by the product has fewer defects and a high rate of finished products. This series of products have already replaced the similar products abroad and been widely used in manufacturing of sapphire, laser crystal (YAG), artificial gem and so on.
