Catalyst Inorganic Chemicals Nickel Carbonate CAS 3333-67-3 Printed Circuit Board Plating​ ​ Introduction: Nickel carbonate is a light green crystal at room temperature. It is almost insoluble in water, more soluble in water containing CO2 than pure water, soluble in ammonia water and dilute acid, and insoluble in cold concentrated hydrochloric acid and nitric acid. When strongly heated in the air, it generates oxides. It reacts with ammonium chloride solution to produce CO2

Colorless Liquid Hexafluorosilicic Acid Cas 16961-83-4 Using for Inorganic Fluorine Disinfectant Introduction: Hexafluorosilicic acid is a kind of inorganic acid. It is majorly used for the fluoridation of water in United State to minimize the incidence of dental caries and dental fluorosis. For chemical synthesis, it is majorly used for the manufacturing of aluminum fluoride and cryolite as well as many kinds of hexafluorosilicate salts. It can also be used for the
