Product Description:
This Potassium Silicofluoride is non-flammable and toxic. Ingestion or inhalation of dust can be poisoned. Dust can strongly irritate the eyes and respiratory system. It will emit irritating and corrosive hydrogen fluoride and silicon tetrafluoride gas when reacts with acid.
Formula: K2SiF6
CAS No: 16871-90-2
M.W: 220.25
Physicochemical properties
The Potassium Silicofluoride is white crystal or powder, which is odorless and tasteless. The hexagonal crystal has a relative density of 3.08, the cubic crystal has a relative density of 2.665 (17 ° C), slightly acidic. It is hygroscopic, slightly soluble in water, soluble in hydrochloric acid, the solubility increases slightly with increasing temperature. It is insoluble in alcohol. Hydrolyzed to potassium fluoride, hydrogen fluoride and silicic acid in hot water. It decomposes into potassium fluoride and silicon tetrafluoride when burned, which is poisonous.
Application: The Potassium Silicofluoride can be applied for wood preservation, ceramics made, metallurgy of aluminum and magnesium, optical glass, synthetic mica and antisepsis.
Storage: Store at a ventilating, and dry place, keep away from food.
Packing: in net 25kg bags.
