Evaluation of the Corrosivity of CaF 2 in Hot Water and 10mol%HF Solution

Evaluation the corrosivity of CaF2 in hot water and 10mol%HF solution was studies.Theprepared powder and sintered ceramic was characterized by XRD and SEM technologies. we could conclude that impurities (such as CaO and CaCO3) effected the porperties of CaF2, the grain size is smaller, the corrosion resistance is lower. The CaF2 of corrosion resistance was stronger in HF solution than hot water.
