Silica Sand
Silica sand, also known as quartz sand or industrial sand, is a form of silicon dioxide (SiO2) and is one of the most abundant materials on Earth. It is obtained by processing quartz crystals from different sources and is available in various types and grades. Silica sand possesses several desirable properties, including low thermal expansion coefficient, making it suitable for applications involving exposure to high temperatures.
Uses of Silica Sand:-
Silica sand finds widespread application in various industries due to its unique composition and qualities. Here are some key uses of silica sand:
Glassware Industry: Silica sand is a crucial component in the manufacturing of glass.
