Natural Silica sand
Natural Silica sand
Silica sand is recognized for its high chemical purity, with SiO2 content exceeding 99.5%. Due to its high melting point, it is an ideal material for use in foundries. For industrial and manufacturing purposes, silica deposits yielding products with at least 95-99% SiO2 are preferred. Silica is hard, chemically inert, and has a high melting point, thanks to the strong bonds between its atoms.
