Soda ash dense is the grade preferred for glass manufacture because its granular properties make it widely dust-free and reduce the risks of segregation during transport and handling. Sodium carbonate (Na2CO3) is used in the glass and silicate industries and also in metallurgy for its sodium oxide content (Na2O) and for its properties as a flux. It is also widely used as an alkaline reagent for the neutralization of acids and mineral or organic acid salts. Usage: Mainly used in the glass manufacturing and crystal production industries as a melting aid. Packing: 50kg bags, 1200kg jumbo bags.
