Quartz Lumps, Grade : Industrial Grade

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 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, 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%+ 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.
Paint industry
PAINT formulators select micron-sized industrial sands to improve the appearance and durability of architectural and industrial paint and coatings. High purity silica contributes critical performance properties such as brightness and reflectance, color consistency, and oil absorption. In architectural paints, silica fillers improve tint retention, durability, and resistance to dirt, mildew, cracking and weathering. Low oil absorption allows increased pigment loading for improved finish color. (Floor paints that will be subjected to abrasion may contain fine quartz sand as a filler).Not all paints include fillers. It can be used in mesh size (30, 40, 50, 60, 80, 100, 120, 150, 200, 250, 300, 350, 400).
Oil well drilling
In Oil well drilling industry, it is known as Silica flour. It is used for cementing purpose to inhibit strength retrogression at elevated temperatures. It can also contribute as a cement extender by increasing low shear viscosity and preventing cement sedimentation. The addition of silica flour can adjust the phase transformations and inhibit this strength reduction and the associated increase in permeability that occurs in set Portland cement.
