Magnesium FluorosilicatePhysical chemistry properties: white rhombus or acicular crystal, odorless. Its density is 1.788, melting point is 120°C, may lose crystallize water by efflorescence, soluble in water, thin acid, insoluble alcohol thin soluble in silicofluoride. Its water solution appears acidity it can produce fluoride and silicon dioxide with alkali, poisonous.
Magnesium FluorosilicateUsage: it can improve the hardness and strength of concrete. It is excellent harden and waterproof matter, and insecticide.
