Sodium Silicofluoride

Sodium Silicofluoride 99%Min - Product Identification CAS No. : 16893-85-9 H.S. Code : 2826.901000 Formula : Na2SiF6 Molecular Weight : 188.06 Toxicity : highly toxic to all plant and animal life Synonyms : Sodium Silicofluoride; Sodium Hexafluorosilicate; Sodium Fluosilicate; Earwig Bait; Disodium Hexafluorosilicate Raw Materials : fluorosilicic acid with sodium carbonate - Physical And Chemical Properties Physical State : (Apperance) It is colorless hexagonal, odorless and 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 and produces sodium fluoride and silicon dioxide. It is decomposed to sodium fluoride and silicon tetrafluoride by heating to 300'C. It is noxious! Specific Gravity : 2.679 Solubility in Water : 0.76 g/100 ml at 25 C , 2.45 g/100 ml at 100 C - Applications It is used as antiseptic in timber industry, hygroscopic agent of acid-resisting concrete, solidifying agent in natural latex products, additive in plating with zinc, nickel, iron and filler in plastic and fluorinating agent in pharmaceuticals and drinking water. It is used to produce insecticide in pesticide industry and sodium fluoride in man-made cryolite. - Specification Quality Standard : HG/T3252-2000 Appearance : It is colorless hexagonal, odorless and tasteless crystal Testing Items : Quality Standard Reference Testing Results Purity (NA2SIF6) DRY BASIS : 99.0%Min / 99.53%Min Loss on Drying At 105Oc : 0.3%Max / 0.14% Free Acid(Based on HCI) : 0.1%Max / 0.032% Water-Insoluble Matter : 0.40%Max / 0.32% Heave Metal(Based on Pb) : 0.02%Max / 0.015% Iron(Fe) : 0.02%Max / 0.014% Fineness(Through 250um test bolter) : 90.0%Min / 95% - Transportation Storage : Store at a ventilating, and dry place, keep away from food.
