Purity 99% Intermediate Ammonium Hexafluorosilicate CAS 16919-19-0

Products Description

Ammonium Hexafluorosilicate is an important inorganic compound. Other names include ammonium fluorosilicate and ammonium silicofluoride. Its molecular formula is F6H8N2Si, its molecular weight is 178.15, its CAS registration number is 16919-19-0, and its EC number is 240-968-3. Ammonium Hexafluorosilicate appears as colorless crystals or white powder, and has two crystal structures: α and β. The α type is an isometric crystal system with a density of 2.01g/cm³; the β type is a triclinic crystal system with a density of 2.15g/cm³. It is stable in the air and is soluble in water and ethanol, but insoluble in acetone. Under high temperature conditions, the β type will gradually transform into the α type.
