Product Name: High Purity Potassium Carbonate
Molecular: K2CO3
Molecular Weight: 138.19
CAS: 584-08-7
Melting Point: 891 degree

Introduction: The molecular formula of potassium is K2CO3, the relative molecular weight is 138.19, it is monoclinic crystal in nature, existing in the form of white powder of fine particles or round spherules. The relative density is 2.428 and its melting point is 891. It is easily dissolved in water; The aqueous solution is in the state of alkalinity. It can not be dissolved in ethanol and aether. It has the characteristics of hygroscopicity, and can be changed to clumps, which changes to potassium acid carbonate when it contacts carbon dioxide in the air.

Use: Potassium Carbonate is an important abio industrial chemicals, which is mainly used in television glass envelope, carbon removal of chemical fertilizer, electric welding rod, pharmacy, aquae hydrogenii dioxide, cine film, porcelain enamel, printing and dyeing, potassium and other fields. When potassium used in foods is put into food of flour, it can effectively improve the taste and quality of food, meanwhile, it is the raw material of food additive used in potassium sorbate and sweet elements.
