Soda Ash

FULL NAME : Soda Ash (Sodium Carbonate)

Product Specifications

Properties

• Alkalinity: Its aqueous solution is strongly alkaline, though weaker than sodium hydroxide (caustic soda). It is an important inorganic base.

• Thermal Stability: Stable at high temperatures but begins to decompose around 850°C.

• Hygroscopicity: The anhydrous form readily absorbs moisture and carbon dioxide from air, caking and forming sodium bicarbonate.

• Reactivity: Reacts with acids to form salt, water, and carbon dioxide; reacts with metal ions like calcium and magnesium to form carbonate precipitates.

Main Uses

1.Glass Manufacturing: 

•  The largest consumption sector. As a primary raw material (supplying Na₂O), it lowers the melting point of silica sand for producing flat glass, container glass, etc.

2.Chemical Production: 

•  Used to manufacture various sodium salts (e.g., sodium silicate, sodium phosphate, sodium chromate), baking soda (sodium bicarbonate), monosodium glutamate, etc.

3.Detergents & Soaps: 

•  Used as a builder to soften water and enhance cleaning power in laundry detergents, soaps, and industrial cleaners.

4.Metallurgical Industry: 

•  Used as a flux in ore processing and metal smelting (e.g., tungsten extraction).

5.Water Treatment: 

•  Used for pH adjustment, industrial water softening, and neutralizing acidic wastewater.

6.Pulp & Textile: 

•  Used in paper pulping liquors and textile post-dyeing treatment to remove impurities and adjust pH.

7.Food Industry: 

•  Used as an acidity regulator, leavening agent, and processing aid (e.g., in noodles, pastries) in compliance with food-grade standards.
