Synonyms : Sodium Silicofluoride; Sodium Hexafluorosilicate; Sodium Fluosilicate; Earwig Bait; Disodium Hexafluorosilicate
Raw Materials : fluorosilicic acid with sodium carbonate

- Physical Chemical Properties
Physical State : (Apperance) It is colorless hexagonal, odorless tasteless crystal with relative density 2.679. It is hygroscopic. It is soluble in ether, insoluble in alcohol. The solubility in acid is greater than in water. It decomposes in alkaline solution produces sodium fluoride silicon dioxide. It is decomposed to sodium fluoride silicon tetrafluoride by heating to 300'C. It is noxious!
