1. White Micro Silica Fume Introduction
Zirconia silica fume, a compound of zirconium dioxide, zirconium oxide melting products, also called silicon ash. This Zr silica fume is derived from the same zircon used to make fused Zirconia, and is captured from the furnace during the fusion process. It not only has the general characteristics of silica, but also has a certain amount of zirconia powder. Silica fume, also known as microsilica or silica dust,is a by-product of the reduction of high-purity quartz with coke in electric arc furnaces in the production of silicon and ferrosilicon alloys(ASTM C1240,EN13263),Its used in concrete field widely.
