True specific gravity 2.533 (20�°C), bulk density 0.90min. Easily soluble in water, Maximum solubility at 35.4�°C. The aqueous solution appears strong alkalinity. On exposure to air it easily absorbs moisture, carbon dioxide, and gradually forms sodium bicarbonate (caking soda).
Usage:
1.The manufacture of glass is one of the most important uses of sodium carbonate. When it is combined with silica (SiO2) and calcium carbonate (CaCO3) and heated to very high temperatures, then cooled very rapidly, glass is produced. This type of glass is known as soda lime glass.
2. Soda ash also is used to clean the air and soften water.
3. Manufacture of Caustic Soda and dyestuffs
4. metallurgy (processing of steel and extraction of iron etc),
5. (flat glass, sanitary pottery)
6. national defense (TNT manufacturing, 60% gelatin-type dynamite ) and some other aspects, such as rock oil refining, paper manufacturing, paint, salt refining, softening of hard water, soap, medicine , food and so on.
Sodium Carbonate or Soda Ash It is used to manufacture a variety of glass products such as container glass for packaging, float glass for buildings and automobiles, fiber glass for insulation, etc.
in Soap and Detergent It is used as a filler, pH adjuster, agglomerate aid, and water softener to manufacture soaps and detergents.
It is also used to prepare sodium silicate, in photograph development process as a pH regulator, swimming pools to neutralize the excess chlorine, brick industry as a wetting agent, processing non- ferrous metals, etc.
Properties : white crystal powder, easily soluble in water, water solution is alkali. Easily absorbing moisture and co2 if exposing in the air.
Applications: mainly used in glass-manufacturing, chemical industry, metallurgy, paper, dye, synthetic washes and petrochemistry.

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.

Soda Ash Dense has a higher density lowers the temperature at which sand melts when making glass. Glass that uses soda ash is flat glass (windows, automotive, mirrors) and container glass (food and beverage bottles, tumblers and serving dishes). Soda ash is also used in detergents, directly as a water softener in dry mix, and as a raw material for other detergent chemicals. Soda Ash is used for neutralization (lead-acid battery recycling, environmental acid controls) and in aluminum manufacturing. In addition to being a fundamental ingredient in glass manufacturing, soda ash is necessary to petroleum refining, pulp and paper production. Soda ash is one of the ten highest volume minerals produced in North America and constitutes nearly 25% of every pound of glass manufactured. It�?�¢??s used in Ceramics, chemical reagents, soaps, electroplating, metal cleaning, paper coating, enameling, and other general chemical uses.
