Properties

Sodium fluorosilicate can be used as insecticide in agriculture, opal for enamel, corrosion agent for opal glass, preservative for wood and raw material for manufacturing other fluorides. It is also used in smelting beryllium and aluminum, medicine, leather and rubber industries. It can be used as accelerator of water glass bond in refractories. Due to the low solubility of sodium fluosilicate in water, the reaction between sodium fluosilicate and water glass is slow and gradual, which is not only beneficial to the construction, but also has high density and strength. It is most commonly used in inorganic materials combined with water glass.
