Quartz is commonly known as silica sand for producing oat glass, ber glass, automotive glass, clear container glass, Borosil glass and other types. We produce quartz powder for high purity glass having extremely low levels of contaminating metal oxides, and other foreign particles with the help of heavy magnetic separators used in mesh 25 to 32 or in mm size 0.1mm-0.3mm, 0.3mm – 1.2mm, 0.5mm-0.1mm, 1.2mm – 0.3mm.
Fused Quartz (Silica glass), vitreous silica glass: silica (SiO2) is used for very special applications and has very low thermal expansion, is very hard and resists high temperatures (1000 1500 C). It is also the most resistant against weathering (alkali ions leaching out of the glass, while staining it). It is used for high temperature applications such as furnace tubes, melting crucibles, Flat glass, Automotive Glass Hollow Glass (e.g. Thermal expansion, hardness, specic gravity).
