Zinc fluorosilicate

CAS: 16871-71-9
Molecular Formula: F2O4Si2Zn
Molecular Weight: 223.5744
Product description:Colorless hexagonal system prismatic crystal or white crystalline powder.Soluble in water, soluble in mineral acids, insoluble in ethanol.Neutralization reaction by sulfuric acid, fluorite and silica sand fluorosilicic acid solution (see fluosilicate), reoccupy lead salt purification (lead fluorosilicate or lead carbonate), remove the sulfuric acid root. Then using zinc oxide neutralization, then through filtration, evaporation (to saturated solution), cooling crystallization, centrifugal separation, drying, fluorine zinc silicate was finished.Use for concrete fast curing agent, wood preservative, plaster of Paris after strengthening agent, washing treatment, mothproofing agent, catalyst of polyester fiber production, also used to configure the zinc electrolysis bath.
