摘要： A mixed powder is obtained by adding at least one kind of solid ester wax to an iron-based powder for powder metallurgy use. The mixed powder is molded. The melting point of the ester wax is 100° C. or lower, the quantity of the ester wax added is in the range of 0.02 wt % or more to 0.6 wt % or less, and the temperature of the mold when the molding is performed is set in a range of (the melting point of the ester wax+10° C.) or more to 200° C. or less. The ester wax thereby liquefies on the surface of the mold and bleeds out when the molding is performed. As a result, molded sintered parts with complex shapes, good surface characteristics, and high densities can be easily obtained.

摘要： There are disclosed metallic soap fine particles which have an average particle size of 4 .mu.m or smaller and have a content of particles having particle sizes of 10 .mu.m or larger of at most 4% by weight based on the whole metallic soap fine particles; a process for producing the metallic soap fine particles, comprising mixing (a) an aqueous solution containing 0.001 to 20% by weight of an alkali metal salt or an ammonium salt of a fatty acid having 4 to 30 carbon atoms with (b) an aqueous solution or dispersion containing 0.001 to 20% by weight of an inorganic metal salt at a specific temperature to form a slurry of the metallic soap, and drying the resultant slurry at a specific temperature. The metallic soap, which has remarkably fine particles and narrow particle size distribution, is well suited for use e.g. as a toner additive in an electrophotographic copying machine by virtue of the improvements in blocking resistance, fluidity and eliminability of the toner, and also as a cleaning aid in the same owing to the improvement in cleaning performance for residual toner without impairing the surface of a picture image support.
