Types of Silica Sand - Different Kind of Quartz Sand, Silica Sand

5. Fused Silica Sand. Fused quartz is an extremely pure material featuring very low thermal expansion and excellent optical qualities. Fused quartz is produced synthetically by the vapor phase hydrolysis of a silicon halide. The resulting product is vitreous, non-crystalline, of the highest purity and one of the most transparent glasses made.

Properties of Fused Silica - QSI Quartz

The purities of fused quartz and fused silica are outstandingly high. Synthetic fused silica from Heraeus contains total metallic contamination below 1ppm. For fused quartz the amount is approximately 20 ppm and consists primarily of Al2O3 with much smaller amounts of alkalis, Fe 2 O 3, TiO 2, MgO and ZrO 2. OH content.

Glass 101: Fused Silica vs. Quartz Mo-Sci Corporation

The terms "fused silica" and "fused quartz" are often used interchangeably. More accurately, "fused quartz" refers to an amorphous solid formed by melting naturally-occurring quartz. So, while fused silica is ostensibly pure SiO 2, fused quartz contains impurities depending on the quartz that was used.
