- Product Application:
Widely used in chemical engineering, glasswork, metallurgy, papermaking, printing and dyeing, synthetic detergent, petrochemical, food, medical and health industries, etc.
Glass Industry
The most important use of dense soda ash is in the manufacturing of glass. Soda ash is an essential constituent in this process as it maintains the furnace temperature necessary to melt the silica, thus reducing the energy required to produce glass. It is generally used to supply the bulk of the alkali element because it is the most cost effective source of Na2O.
Chemical Industry
Soda ash is widely used in the domestic chemical processing industry. It is a source of sodium ions in the production of sodium phosphates, sodium silicates, chrome chemicals and photographic chemicals. It’s also used in the production of sodium bicarbonate (also known as baking soda), which is an essential ingredient in beverages, coatings, detergents, food, dialysis, and personal care markets.
Paper Industry
Soda Ash is used in paper making, to soften the wood chips and control the pH level in the pulp cooking process.
Other Applications
Soda ash is used in water treatment at the domestic stage as it helps control the water’s pH levels and also softens it. It is also used in soap and detergent industry though soda ash light is preferred over soda ash dense in detergent industry.
