Quartz lumps

We supply Quartz in Lumps, grits/Sands and powder forms for various industrial applications:- Quartz sand/grains in Glass Industry:- Quartz is commonly known as silica sand for producing float glass, fiber 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 & 186C). 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, specific gravity). Ceramics Industry It is used for fireproof ceramics, fine ceramics, tableware floor and wall tiles, sanitary ceramics, porcelain and glazes. In the CERAMIC body, silica is the skeletal structure upon which clays and flux components attach. The SiO2 contribution is used to modify thermal expansion, regulate drying and shrinkage, and improve structural integrity and appearance. Quartz powder is also used in ceramic tiles along with feldspar. The powder is available in semi and snow-white color, which has 90 Percent+ whiteness that is considered “A” grade, and is mostly used by table ware manufacturer because of extra whiteness and non-contamination. However in ceramics, huge quantities of quartz powder are used in bodies and glazes. Usually 200, 300 & 325 meshes are used.
