    摘要: Methods for preparing iron source material and ferrous oxalate for lithium ferrous phosphate are disclosed. One method comprises bringing solution containing ferrite and soluble non-ferrous metal salts in contact with oxalate solution; wherein said method of contact is to allow a flow of the ferrite solution containing ferrite and soluble non-ferrous metal salts to come in contact with a flow of oxalate solution. Another method comprises brings a stream of ferrite solution in contact with a stream of oxalate solution, wherein the flow rates of the ferrite solution and oxalate solution give the resulting slurry a pH of 2-6. The ferrous oxalate particles produces by the methods of the present invention are regularly shaped and have small and evenly distributed diameters. Lithium ferrous phosphate made from iron source material and ferrous oxalate prepared using the methods of the present invention has small particle diameter, homogeneous particle size, good electrical conductivity, and superior electrochemical properties.

    摘要: The present invention discloses a method and a device for preparing a compound semiconductor film. The method comprises the steps of: providing a substrate above at least an evaporation source in a vacuum condition; heating a source material contained in the evaporation source so that the source material is vapor-deposited on the substrate; and taking out the substrate under protection of an inert gas. The substrate may be rotated around an axis of a plane where the evaporation source is positioned, and the substrate is tilted by a predetermined angle with respect to the plane. The compound semi-conductive film thus prepared has a uniform thickness with a larger area. The method provides a simplified process and enhanced efficiency.
