Product Application of Sodium carbonate CAS#497-19-8
A major application of sodium carbonate is in the glass industry, where it acts as a fluxing agent to reduce the melting temperature of silica, with a significant proportion of global production being consumed for glass manufacturing. Beyond glass production, sodium carbonate is widely used as an alkaline agent in industries such as pulp and paper manufacturing, textile processing, water treatment, and the production of soaps, detergents, and cleaning products. It is also applied in food processing, chemical synthesis, laboratory applications, and the treatment of certain metals and compounds. Due to its versatility, cost-effectiveness, and excellent alkaline properties, sodium carbonate remains an essential raw material for both industrial and household applications.
