Factory Price SiO2 Silica Fume CAS 14808-60-7 For Construction Silicon Dioxide

Ordinary quartz sand is used in the manufacture of flat glass, daily-use glassware, and similar products; refined quartz sand is utilized in the production of optical glass and instrument glass; meanwhile, high-purity quartz sand (low-iron quartz sand) is employed in the manufacture of photovoltaic glass (ultra-clear glass) and photovoltaic crucibles, serving as a critical raw material for the photovoltaic industry.

It constitutes a primary raw material for molding sand in the foundry industry, used to create sand molds and cores; it is characterized by its high-temperature resistance, high strength, and excellent permeability. In the refractories industry, quartz sand is used to manufacture silica bricks, lightweight silica bricks, and similar products, leveraging its high refractoriness and acid resistance.

Ordinary quartz sand is frequently used in wastewater treatment, while refined quartz sand is commonly employed in the pretreatment stages of pure water production.

In fields such as electronic information, semiconductors, and fiber-optic communications, it is used to manufacture semiconductor chips, optical fiber preforms, quartz glass fibers, optical lenses, and specialized light sources—applications that impose extremely stringent requirements regarding purity and impurity levels.
