Soda ash

Key Attributes.

The Soda Ash is produced using the amonia-soda process popularly known as Solvay process. The common salt and lime are the raw materials processed and converted in to soda ash and calcium chloride. Light soda ash is a white, odorless, uniform product, free from the atmosphere. The moist soda ash then starts absorbing the atmospheric carbon dioxide. This phenomenon of absorbing moisture and carbon dioxide by soda ash is known as weathering. After such weathering, soda ash is likely to contain appreciable moisture and sodium bicarbonate. However the total alkali content of the bag does not change. Soda ash has a tendency to cake when in contact with moisture and consequently becomes lumpy. Light soda ash is one of the most important basic industrial chemicals and the most widely used fixed alkali for manufacture of other alkali products, sodium salts, glass, soap, sodium silicates, detergent, bicarbonates, bichromates, pulp and paper, cellulose and rayon, iron and steel, aluminium, cleaning compounds, water softening chemicals, textiles and dyestuffs, drugs, and many other materials. It also finds extensive use as an alkali for household purposes and as a washing powder by laundries and washerman.
