Abstract:
    The microwave process of preparing ferrous lithium phosphate with ferric phosphate includes the following steps: 1. mixing reduced iron powder, lithium phosphate and ferric phosphate in the molar ratio of 0.9-1.1 to 0.9-1.1 to 1.8-2.2, high speed ball milling for 2-10, tabletting and roasting in a tubular furnace in inert atmosphere or vacuum condition at 300-500 deg.c for 4-12 hr to obtain the precursor; and 2. ball milling the precursor for 1-6 hr, tabletting, setting into crucible and covering with medium, heating in a microwave oven of 350-700 W power for 2-12 min, ball milling for 2-6 hr, and 400 mesh sieving to obtain ferrous lithium phosphate product. The ferrous lithium phosphate product has excellent performance, homogeneous phase, small grain size and other advantages.
