Inorganic Chemicals
Description
Sodium Silicofluoride 99%Min
- Product Identification
CAS No. : 16893-85-9
H.S. Code : 2826.901000
Formula : Na2SiF6
- 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& acute;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.
