What is QUARTZ?
Silicon (Si) does not occur in a free state in nature, but its compounds are extraordinarily abundant and constitute about 28 percent of the Earth’s crust.
Quartz is a hard, crystalline mineral composed of silicon and oxygen atoms (silicon dioxide). It is one of the most useful and second most abundant minerals found on earth crust after feldspar. Deposits of Quartz are found across all continents and occur in all types of rocks, including igneous, metamorphic, and sedimentary. Quartz in its purest form is clear or white in color but different impurities within the atomic lattice can cause the color to change to purple, pink, brown, black, grey, green, orange, yellow, blue, or red and in some cases, multi-color. Devoid of cleavage, it breaks with irregular fracture. Quartz crystals of pure, untwined, clear, and transparent varieties possess piezoelectric properties.
Quartz has many commercial applications, and therefore Quartz must undergo a careful, and an extensive process to ensure maximum product yield. Quartz Processing usually includes crushing, grinding, washing and screening. These steps strip off physically associated impurities and water-soluble impurities and give a relatively uniform and small particle size material for its future use.
High Melting
Quartz endures high heat up to 1650℃, ideal for silicon melting furnaces.Low Temperature
Quartz, with silica’s structure, endures temperature changes, expanding in various temp.Unreactive
Fused quartz crucibles, being chemically inert, do not react when exposed to most other chemicals, including most acids.Chemical Purity
High-purity quartz prevents metal contamination, vital for semiconductor industries
