Formula MgSiF6 Molecular 274.48
Execute standard 2853 U.N-NO 2853
Class 6.1 H.S-NO 2826.9000.9007
Properties It is a colourless or white rhombus or acerose, odorless crystal. d 1.788.It is not easily deliquescence, but effloresce to lose crystal water. It is dehydrated at over 80℃ and gives out gas of silicon tetrafluoride. It is easily soluble in water, soluble in dilute acid, hardly soluble in hydrofluoric acid, insoluble in alcohol. Its aqueous solution appears acidity. It reacts with alkali to form corresponding fluoride and silicon dioxide. It is noxious!
Usages It is used as hardening agent and waterproof agent for concrete to improve rigidityandintensity,in handling fluoride efflorescence of silica building, in ceramic industry. It prevents and kills off insect pests from textile. It is used as insecticide etc.
Packing In 25kg and 50 kg plastic woven bag lined with high pressure polyethylene plastic bag.
