Calcium silicate with quartz powder is the number of requirements! How much silicon content?
Calcium silicate board preparation of quartz powder with the general requirements:
Silica content: greater than or equal to 93 (%)
Melting point 1600 (℃)
Mohs hardness: conventional
Common specifications: 100 - 325 head
Color: gray, grayish yellow
Suitable for the production of calcium silicate board and other calcium silicate products
Should be greater than 95 (%) above the silica 325 mesh wet quartz powder is best high purity
93% content is enough, about 400 mesh, the price of 200-250 yuan / ton, water mill purity is higher, but the same can be used.
