Effect of Different CaF₂ Powder on Micromechanism and Dissolution Rates of CaF₂ Block

Abstract:

CaF₂ could be used as inner protection liner material of the cavity which is chemical etched by H₂O and HF. This is because CaF₂ is not easy deliquescence, corrosion resistance and self-lubricating properties. This paper mainly analysis and research the three kinds of powder form different manufacture factory. The powder is burned in the air at 1360°C for 0.5h, the result display that the density of block we get after a powder is burned is the biggest and the width of the peak gets narrow after were calcined, which indicates the crystallinity has improved. The powder did not react with water at 90°C,but the powder was burned react with water at 90°C。
