Product Description

Product Description

Heavy soda ash, also known as dense soda ash, is primarily composed of sodium carbonate (Na2CO3). It is an anhydrous compound that appears as fine white granules, with a relatively high density, typically ranging from 1000 to 1200 kg/m³. Heavy soda ash is produced by hydrating (adding crystal water) or compressing light soda ash (light alkali), resulting in a higher bulk density and better physical stability.
Chemical Properties
• Solubility in Water: Heavy soda ash is highly soluble in water. Its aqueous solution is strongly alkaline (with a pH of approximately 11.6) and can undergo neutralization reactions with acids to produce corresponding salts and carbon dioxide.
• Stability: It is relatively stable at room temperature but can decompose into sodium oxide and carbon dioxide at high temperatures. When exposed to air for extended periods, it absorbs carbon dioxide and moisture, gradually converting into sodium bicarbonate.

Application

In the metallurgical industry, heavy soda ash is primarily used as a flux in the smelting and refining of ores:
• Steel Production: It is used to remove impurities from ores and improve the efficiency of ore smelting.
• Non-ferrous Metal Smelting: In the production processes of metals such as aluminum and zinc, heavy soda ash can act as a flux to lower the smelting temperature and increase the recovery rate of metals.

Heavy soda ash is one of the indispensable raw materials in glass production. It is mainly used to provide sodium ions, which lower the melting temperature of glass. This, in turn, reduces energy consumption and improves the transparency and quality of the glass. Specific applications include:
• Flat Glass: Used in the production of architectural glass, automotive glass, and more.
• Glass Fibers: Used to manufacture insulating materials and reinforced composite materials.
• Household Glass: Such as glass bottles, glassware, and more.

During the leather-making process, heavy soda ash is used for defatting and cleaning leather:
• Defatting: It removes oils from the surface of the leather, making it softer and more uniform.
• Cleaning: It is used to wash the leather, removing impurities and stains, thereby improving the quality of the leather.
