Heavy Soda Ash powder has the particle size about 250-450 microns with average particle size of 350 micrometers. Heavy Sodium Carbonate is used in glass industry, pH adjustment, soda production, detergent production, water hardness prevention and paper and pulp industries. This powder is soluble in water and its solubility increases with increasing of water temperature.
From the combination of Heavy Sodium Carbonate with water, a strong alkaline solution with a pH of about 11.5 is formed. This is due to the presence of Sodium and the Alkaline composition of the powder, especially Sodium Hydroxide. The resulting aqueous solution of Heavy Sodium Carbonate is a very strong base. This solution reacts very strongly with a large number of acids. This base solution decomposes in presence of heat and emit Disodium Oxide (Na2O), which is extremely harmful to the respiratory tract.
Production of Heavy Soda Ash
Light Soda Ash is converted to sodium monohydrate when hydrated. In the continuation of this process, by removing the water, a higher density product is obtained, which is called Heavy Soda Ash. This material has larger and denser crystal sizes. Heavy Sodium Carbonate can be obtained from several methods. One of the old and important methods is the Solvay method. In this method, raw materials of Lime, Sodium Chloride and Ammonia are used.
