UN No.:
HAZARD CLASS :
H.S.CODE:
Molecular weight ?220.27
[Properties]: It is white 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).
