Fused Silica – Sibelco

Mineral: Fused Silica. Fused silica is an angular “shaped” silica produced by grinding and milling (ball-mill) high purity silica/quartz. Fused silica therefore has the same intrinsic properties as any other silica. Its chemical formula is SiO 2. At Sibelco high purity quartz is being used to make fused silica.

The effect of alumina contamination from the ball-milling ...

Jun 01, 2011  Several grades of fused silica were analysed for their alumina content. The finer the material, the longer the mill time attributed to the material. Hence, an arbitrary value of time was associated with each fused silica grade, with 1 being the coarsest material, milled for the least time, and 5 being the finest material, milled for the longest.

Silica - Digitalfire

Thus, a typical high temperature stoneware glaze for potters might have 30% silica whereas a fast-fire industrial glaze might have none. If you are a potter and one of your glazes has 30% silica, you really should be ball milling it. If you are firing at low temperatures, these principles are even more important.
