Silica Sand/Quartz Sand – Sand International

Silica Sand also well known as Quartz Sand. It was got from the broken and ground Silica Stone/Quartz Stone. Quartz sand is an important industrial mineral raw material, non hazardous chemicals, widely used in glass, casting, ceramics and refractories, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive and other industries.

Quartz Uses

Silica based quartz sand is often used as foundry sand which is blended with cohesive agents such as clay and oil, among others, and then used for the purpose of molding and casting. Also, any crude edges on metals after they have been cast, cut or drilled is also burred or removed with the help of microcrystalline quartz.

Silica Statistics and Information

Silica Statistics and Information. Industrial sand and gravel, often called "silica," "silica sand," and "quartz sand," includes sands and gravels with high silicon dioxide (SiO 2) content. These sands are used in glassmaking; for foundry, abrasive, and hydraulic fracturing (frac) applications; and for many other industrial uses.
