Quartz is a hard, crystalline mineral composed of silica. The atoms are linked in a continuous framework of SiO4 silicon oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO2. Quartz is the second most abundant mineral in Earth's continental crust. It is hard, brittle, transparent material with a density of 2649 kg/m3 and a melting point of 1432°C. This naturally available quartz is mined by the company and processed for achieving the various size fractions as per customers requirements. Once the high purity Quartz is procured from the mines, the material undergoes manual sorting, advanced colour sorting, state- of the- art magnet systems, proper sizing with high frequency vibrations to achieve the best material. Application industries: Engineering stone Semiconductor Glass Refractory Ceramics
Quartz sand of Pakistan origin. Used in glass products such as solar panels, window panes, and laboratory equipment. Quartz sand abrasive grade, water filter grade, available in the following sizes:- 0.1 - 0.4 mm 0.4 - 0.7 mm 0.7 - 1.2 mm 1.2 - 2 mm
Quartz Grits Grade A & B Color: Milky & Glossy white and off white Available almost all sizes
Fused silica is a glass consisting of pure silica (SiO2) in amorphous form. Fused quartz has high working and melting temperatures, making it less desirable for most common applications. Fused silica is a glass consisting of pure silica in amorphous form. Applications â?? Electrode flux coating Optical components
