Potassium Silico Fluoride
Properties of potassium silicofluoride K2SiF6: It is white crystals or powder, odorless, tasteless and weak acidic and have toxic. The density of hexagonal crystal is 3.08.It is hygroscopic.It is slightly soluble in water, soluble in hydrochloric acid. Its solubility is slightly higher as the temperature gets higher. It is decomposed by heat to form potassium fluoride(KF) and silicon tetrafluoride(SiF4). It is hydrolyzed in hot water to form potassium fluoride(KF),hydrogen fluoride(HF) and silicate acid(H2SiO3).Usage of potassium silicofluoride K2SiF6: It can be used as wooden preservatives and insecticides, or to produce synthetic mica and opalescent glass.It can also be used as flux in metallurgy of magnesium and aluminium.
