SODIUMCARBONATE
SODA ASH BUY IN UKRAINE
Sodium carbonate (soda ash) is an inorganic compound, the sodium salt of carbonic acid with the chemical formula Na2CO3.
Technical soda ash is produced in the form of granules and powder. It quickly dissolves in water, does not have a characteristic odor. This substance has a low density of 2.54 g / cm³, it can only boil at a temperature of 1600 ° C.
Soda ash is used in the production of glass (including crystal), ceramics, stained glass, synthetic detergents, acids, salts, paints, varnishes, etc.
The metallurgical industry uses sodium carbonate to produce iron, lead, zinc, chromium, and other metals. Its action is to neutralize the environment and purify the exhaust gases during production. Soda is also a softener in the processing of industrial water, used in soap making and in the manufacture of paper.
