Preparation and Properties of CaF₂ Nano-Powder

Abstract:

CaF₂ nano-power was prepared by direct precipitation methods with Ca(NO₃)₂and KF as raw materials. The influences of presintering temperature and sintering temperature on the particle size and distribution of CaF₂nano-power were studied by X-ray diffraction (XRD) and field-emission scanning electron microscopy (FESEM). This study provided an experimental method for preparation of CaF₂ nano-power. The results show that the best presintering temperature of CaF₂ nano-power is 500°C and the best sintering temperature of CaF₂ ceramic is 900°C.
