Application Summary AI generated

This standard specifies two methods for determining silicon dioxide content in limestone and dolomite: the silicomolybdic blue spectrophotometric method for low silicon levels and the perchloric acid dehydration gravimetric method for higher silicon content. It is applied in the mining and mineral processing industries for quality control of raw materials used in cement, metallurgy, and construction. The standard ensures accurate chemical analysis during exploration, production, and product certification of these carbonate rocks.
