Application of Sodium Fluorosilicate:

Widely use in opal glassware and lamp pendantlamps production.

Sodium Fluorosilicate is designed for pesticides, milk whitening agent

for enamel, corrosive agent for milk white glass, the anti-corrosive

agent for timber and other fluoride raw materials. It's also used in

smelting of beryllium and aluminum, as well as medicine, rubber, and

leather industries, etc
