Description

Aluminium Hexafluorosilicate is an inorganic salt primarily used as a source of fluoride and silica in various industrial processes. This compound is valued for its role in enhancing material properties and facilitating specific chemical reactions. It is a key material for manufacturers in the ceramics, glass, and metal surface treatment industries, where controlled fluoride release is required.

Application

As a fluxing agent and opacifier in the production of specialty glass and ceramic glazes.
In metal surface treatment and aluminum anodizing processes to improve coating quality and corrosion resistance.
As a precursor or additive in the manufacture of synthetic mica and other silicate-based materials.
In water fluoridation and as a component in certain industrial cleaning and etching formulations.
For the synthesis of other fluorosilicate compounds used in research and specialty chemical production.
As a hardening agent or additive in specific construction material formulations, such as certain cements.
