) is known as light soda ash (solid density 1.86). Dense soda ash has solid density of 1.91. Both grads (lightly and dense) are granular. Na 2 CO 3. 10H 2 O is known as washing soda. USES Widely used in the manufacture of glass, Used in manufacture of sodium bicarbonate, caustic soda, Used in soap, pulp and paper, textiles industries
May 25, 2015· Sodium carbonate is known as washing soda or soda ash. It is commonly occurred as a crystalline heptahydrate which readily effloresces to form a white powder, the monohydrate. Pure sodium carbonate is a white, odorless powder that is hygroscopic means it absorbs moisture from air.

The sesquicarbonate crystals are decomposed to sodium carbonate in rotary caliners at approximately 2000C. the anhydrous soda ash product has a bulk density of about 800kg/m3 and must be double calcined to prepare dense ash. After calcinations, the soda ash is cooled and is ready for shipment. (3) Dual process
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. The light grade has a bulk density of ~0,5 t per m3. The D50 of approximately 100 microns is very well suited for detergent and chemical applications.
