Al (OH)3 coated CaF2 composite powder was prepared by coating Al (OH)3 on surface of micro-sized CaF2 particles using heterogeneous nucleation method. Influence of Al3+ concentration, PH value and reaction temperature was studied. The result reveals that CaF2 particle was uniformly coated with a layer of Al (OH)3 and Al3+ concentration, pH value and reaction temperature are the main factors that affect coating result. Optimum technological conditions are Al3+ concentration of solution before reaction at 0.15 mol/L, pH value at 7.5 and temperature at 75 oC.
