Magnesium Carbonate
Magnesium carbonate has many uses, such as manufacturing magnesium salt, magnesium oxide, fire retardant coating, ink, glass, toothpaste, rubber filler, etc., and is used as a flour improver and bread leavening agent in food. In medicine, it can neutralize gastric acid and is used for duodenal ulcer can also be used as alkaline agent, drying agent, color-protecting agent, anti caking agent, carrier, leavening agent and acidity regulator.
