Zinc carbonate is an inorganic carbonate, mainly used as a raw material for the manufacture of ceramics and zinc magnesium white (Lide powder). Zinc carbonate has a low zinc content, and it has a common effect with zinc oxide to activate the accelerator to accelerate the vulcanization rate. However, zinc carbonate is also characterized by better transparency than zinc oxide, no whitening phenomenon, which can solve the problem that zinc oxide is not suitable for transparent products due to its too strong covering power. Generally used in the manufacture of sulfur vulcanized translucent rubber products. Solubility in water (g/100ml) The number of dissolved grams per 100ml of water :4Chemicalbook.692×10-5/20℃ Chemical properties White fine amorphous powder. Odorless, tasteless. Relative density 4.42-4.45. Insoluble in water and alcohol. Slightly soluble in ammonia. Soluble in dilute acid and sodium hydroxide. Reacting with 30% hydrogen peroxide, it releases carbon dioxide and forms peroxide. Application Zinc carbonate is mainly used to make transparent rubber products, zinc white, ceramics and so on. Used as light astringent and raw material for latex products. Used to prepare calamine lotion, used as skin protection agent. It can also be used to produce rayon and catalytic desulfurizer.
