| Use | It is a bulking agent widely applied to the food industry. It is used to produce biscuits, cookies, steamed buns and bread. It is a generator of carbon dioxide in soda water. It can be combined with alum into alkaline baking powder, soda into civilian crystal soda, or used as a butter preservative. It can produce acid-alkali and foam fire extinguishers, rubber and sponge, and used with alum and H pore-forming agent to form pores in the rubber industry. In metallurgical industry, it is used as a fluxing agent for steel ingot casting, a sand-mold molding additive of steel casting in mechanical industry, color fixing agent, acid–alkali buffer and fabric finishing agent in the printing and dyeing industry, and raw material of antacids in the pharmaceutical industry. |
| Properties | It is white crystalline powder, odorless and salty, with density of 2. 159g/cm3. It is soluble in water but ethanol. Its water solution is slightly alkaline. It is stable in dry air and can be slowly decomposed in humid air. It will be hydrolyzed completely above 270℃, release carbon dioxide and become sodium carbonate. |
| Production method | It is obtained after concentrated sodium carbonate solution or crystalline sodium carbonate absorbs carbon dioxide. |
