Glass Grade Silica Sand is reckoned for its excellent wear resistance properties and chemical stability. This tasteless sand is naturally present in amethyst, quartz and chalcedony. Although this sand is brittle, yet it does not crack. It is anisotropic by nature and it can resist fire. Moreover, this specific grade of silica sand can endure alkali and acid. Excellent insulation attributes, UV proof quality, high dispersion level, amorphous quality, less radioactivity level, good mechanical strength, high temperature withstanding capacity and unique suspension attributes are its key features. This silica sand has minimal linear expansion co efficiency level.
This grade is produced as an outcome of high temperature based fusion, cooling, smashing and grading procedures of silica sand. Fused silica lumps are used as raw materials for this fusion
