SODA ASH (Sodium Carbonate-Na2Co3)

What is Soda Ash?

Soda Ash is the 10th most consumed inorganic compound in the world, which has been used for over 5,000 years. It is a safe, simple compound and a key component in a variety of industrial processes from the manufacture of glass to dry powder detergents and lithium-ion batteries. It is also an important ingredient in the food and pharmaceutical industries


How is Soda Ash Produced?

Today, Soda Ash (Sodium Carbonate) is produced by two main methods, both of which produce chemically identical Soda Ash.

  • Natural Soda Ash production:

Natural Soda Ash is produced by mining naturally occurring Trona Ore and then processing this via a simple process of filtering, concentration, crystallization and drying into Soda Ash which can be sold after applying these procedures. Today, this accounts for around 33% of global production. Commercially exploitable Trona deposits only occur geologically in three regions of the world: Enormous deposits in Wyoming, USA, large deposits in Turkey and much smaller and chemically less pure deposits in China.

  • Synthetic Soda Ash production:

By synthetic production methods using either the so-called Solvay or Hou processes, in which salt (sodium chloride) is reacted with either limestone or ammonia, synthetic Soda Ash is produced. This accounts for about 67% of global production.




Soda Ash Different Grades:

  • Dense Soda Ash

Soda Ash Dense – Dense Soda Ash is used in Glass manufacturing (Flat Glass, Container Glass, Plate Glass, deep processing to other high grade glass for example automotive glass, curtain wall glass), Silicate, Ultramarine, and other chemical industries.

  • Light Soda Ash

Soda Ash Light or light Soda Ash is an important basic industrial alkali chemical used in soap and detergents, pulp and paper, iron and steel, aluminum cleaning compounds, water softening and dyeing, in fibre–reactive dyes, effluent treatment and production of chemicals.

  • Washing Soda

an anhydrous substance that’s produced by combining light soda ash along with additional molecules of water. It’s mostly used in soaps and washing detergents to improve their cleaning properties.

Sodium Carbonate Dehydrate (Na2CO3·10H2O), also known as washing soda, is the most common hydrate of sodium carbonate containing 10 molecules of water of crystallization. Soda Ash is dissolved in water and crystallized to get washing soda.

Na2CO3 + 10H2O -> Na2CO3.10H2O

  1. It is white crystalline solid;
  2. It is one of the few metal carbonates which are soluble in water;
  3. It is alkaline; it turns red litmus to blue;
  4. It has detergent properties through the process of saponification which makes fats and grease water-miscible.


Applications of Soda Ash


Since Soda Ash is a soluble substance, it can be used in various chemical reactions – mostly as a coloring agent, detergent, fertilizer, as well as in enameling and petroleum industry.


Glass Manufacture

In the production of glass, glass containers, fiberglass insulation, and many others, Soda Ash is needed especially because it reduces the melting point of Silica.


Detergent Manufacture

Soda Ash can replace the phosphates that are used in making household detergents. Also, there are various cleaning products and dishwashing soaps that contain Soda Ash in their formulations.


Other uses of Soda Ash

  • It can help in removing stains, alcohol, and grease on clothes – also in coffee pots and espresso makers.
  • It can increase the alkaline level in swimming pools which can help in maintaining the PH Levels to balance the water.
  • It can also be used for dying clothes.
  • It can effectively clean the air.
  • It can soften water.
  • It can be used as fertilizers

Indeed, soda ash has a lot of uses and to ensure the quality of the Soda Ash that you’ll use in the manufacture of your products. Make sure to work with a credible glass raw material distributor, like us, Sodis Pour Le Commerce.
