Microsilica

Micro-silica fume is a by product of high purity quartz, coke and sawdust reduction in the production of ferrosilicon or metallic silicon during the production of complex reactions in smelting. Among them, the quartz stone and carbon at 1750 ℃, the reduction reaction to produce unstable carbon monoxide, the temperature is higher than 2160 ℃,

Micro silica Fume for Refractory

The effect of micro silica fume for refractories: High quality microsilica fume has super fine particle size, low water storage and high fluidity. It is widely used in high-performance refractory castables, silicon nitride sintering aids, ladle materials, self-flow refractory castables, preforms, low or no cement castables and dry wet spraying materials. The specific performance and
