Heavy metal(Pb): 0.*1% max Iron(Fe): 0.**5% max

Sulphate(SO4): 0.2% max Free acid(HCl): 0.1% max

Water(H2O): 0.5% max Water-insoluble matter: 0.5%max

Character: It is white crystals or powder, odorless, tasteless and weak acidic and have toxic. The density of hexagonal crystal is 3.*8.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).

Uses: It is used as wood preservationceramics mademetallurgy of aluminium and magnesium, and to manufacture optical glass as kalium glass. It is also used to prepare synthetic mica and antisepsis.

Packing: plastic weaven bag lined with polythene plastic bag,*5kg or ***0kg****0kg per bag.
