Molecular formula：Na2SiF6
Molecular weight：188.06
CAS No.：16893-85-9
Property：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℃. It is
noxious!
Usage：Sodium fluorosilicate is the largest variety of fluorosilicate in construction and building materials industry, mainly used as enamel aid solvent, glass emulsion. 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 rinking water. It is used
to produce insecticide in pesticide industry and sodium fluoride in man-made cryolite.
Packing：Net in 25KG plastic woven bag.
