Quartz Sand

Product Details:

Kedia's Quartz (Silica SiO2) is the most common mineral in the Earth curst. Quartz is found in sandstones, pegmatites granites, and other igneous rocks. It form veins in the crystal looks depends on how hot it was when they form. Crystals are made when the quartz cools down. The way the crystal looks depends on how hot it was when it was when it was formed. It can be found in layers or geodes, too. Geodes are hellow rockes that are lined with crystals. It ha sa hexagonal crystal sturcture and is made of trigonal crystallized silica. It is most varied in terms of varieties, colours and forms. Of all the minerals, quartz is closed to a pure chemical compound and has constant physical properties.

Kedua’s Quartz is a chemical compound consisting of one part silicon and two parts oxygen. It is silicon dioxide (SiO₂). It is the most abundant mineral found at Earth's surface, and its unique properties make it one of the most useful natural substances. It is hard, chemically inert and has a high melting point, attributable to the strength of the bonds between the atoms and extremely resistant to weathering. Quartz may be transparent to translucent and has a vitreous luster, hence it is used in ceramics.
Physical Properties of Quartz
Uses of Quartz :
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. 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.
Foundry Sand : Quartz is very resistant to both chemicals and heat. It is therefore often used as a foundry sand. With a melting temperature higher than most metals, it can be used for the molds and cores of common foundry work.
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.
Oil Well Drilling : In Oil well drilling industry, it is known as Silica flour. It is used for commenting 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.

Product Details:

Kedia’s Quartz (Silica Sio2) is the most common mineral in the Earths crust. Quartz is found in sandstones, pegmatites granites, and other igneous rocks. It forms in the cracks of rocks. There is a lot of heat and water they form. Crystals are made when the quartz cools down. The way the crystal looks depends on how hot it was when it was formed. It can be found in layers or geodes, too. Geodes are hollow rocks that are lined with crystals. It has a hexagonal crystal structure and is made of trigonal crystallized silica. It is most varied in terms of varieties, colors and forms of all the minerals, quartz is closed to a pure chemical compound and has constant physical properties.
Physical Properties of QuartzUses of Quartz
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).
Quartz sand/grains in Abrasive : The high hardness of quartz, seven on the Mohs Scale, makes it harder than most other natural substances. As such it is an excellent abrasive material. Quartz sands and finely ground silica sand are used for sand blasting, scouring cleansers, grinding media, and grit for sanding and sawing.
