摘要
分别采用溶剂 /非溶剂结晶法和机械研磨法探索了超细 BTF粒子的制备。目前采用溶剂 /非溶剂结晶法还难以使 BTF粒子粒径细化至微米级 ;采用机械研磨法获得了平均粒径 0 .74 4 μm、比表面积 19.95 m2 / g的亚微米级超细
Uitra fine BTF particles are explored by machine grinding method and solvent/non solvent crystalling method. Presently, BTF particles's size can not be fined efficiently to sub micron degree by impact crystalling method, while sub micron ultra fine BTF particles can be gained through machine grinding method. Then the sub micron BTF particles whose average particle size is 0.744 μm and its specific surface area is 19.95 m 2/g were prepared using machine grinding method, but the preparation efficiency of mechanical grinder's is rather low and wastage of energy is great.
