Micron Powder
-
High Grade Fused Silica Powder- Micron Powder First Grade High Whiteness with High Purity,Mainly used in Investment Casting, Silicon Rubber. (5UM,7UM&15UM)
Also called A grade Fused silica Powder with high purity Sio2 around 99.7%-99.9%.
High purity quartz stone from Lianyungang,Donghai and Xinyi area was selected as raw material. After pickling treatment, the crystalline silica was transformed into amorphous silica with a small amount of impurity at 1700ºC high temperature in the resistance furnace. After special mechanical processing, screening, iron removal after picking treatment of high purity quartz stones for the formation of blocks, particles and powder products. Fused Micron powder selected the high purity quartz material,which made by terms of purification, grinding,melting,super grinding, precision classification.
