摘要：
The mixed powder for iron-based powder metallurgy of the present invention comprises a powder containing calcium sulfate anhydrite II such that the CaS weight ratio after sintering is 0.01 wt% or more to 0.1 wt% or less. The powder containing calcium sulfate anhydrite II preferably has a volume-average particle size of 0.1 µm or more to 60 µm or less and preferably additionally contains one or more ternary oxides selected from the group consisting of Ca-Al-Si oxides and Ca-Mg-Si oxides. The weight ratio of the ternary oxides and CaS after the sintering is preferably 3 : 7 to 9 : 1.
