China [CN] Sodium Silicofluoride 99%Min- Product IdentificationCAS No. : 16893-85-9H.S. Code : 2826.901000Formula : Na2SiF6Molecular Weight : 188.06Toxicity : highly toxic to all plant and animal lifeSynonyms : Sodium Silicofluoride; Sodium Hexafluorosilicate; Sodium Fluosilicate; Earwig Bait; Disodium HexafluorosilicateRaw Materials : fluorosilicic acid with sodium carbonate- Physical And Chemical PropertiesPhysical 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 : 2.679Solubility in Water : 0.76 g/100 ml at 25 C , 2.45 g/100 ml at 100 C- ApplicationsIt 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.- SpecificationQuality Standard : HG/T3252-2000Appearance : It is colorless hexagonal, odorless and tasteless crystalTesting Items : Quality Standard Reference Testing ResultsPurity (NA2SIF6) DRY BASIS : 99.0%Min / 99.53%MinLoss 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%- TransportationStorage : Store at a ventilating, and dry place, keep away from food.Packing : In 25kg and 50kg plastic woven bag lined with high pressure polyethylene plastic bagHazard Class : 6.1UN No. : 2674- Other Trade InformationMin.
