1. 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 of food, meanwhile, it is the raw material of food additive used in potassium sorbate and sweet elements.
