PCT No. PCT/JP84/00278 Sec. 371 Date Feb. 1, 1985 Sec. 102(e) Date Feb. 1, 1985 PCT Filed Jun. 1, 1984 PCT Pub. No. WO84/04712 PCT Pub. Date Dec. 6, 1984.The invention provides a tin-containing iron base powder comprising iron base particulates each having tin-rich portions on the surface in which at least a part of the tin forms a compound with iron, wherein the total tin content ranges from 1 to 20% by weight of the powder. The invention also provides a process for making such a tin-containing iron base powder by mixing an iron base powder with a powder tin compound capable of generating metallic tin upon thermal decomposition, and heating the mixture to a temperature of 450 DEG to 700 DEG C. in a reducing or non-oxidizing atmosphere. Using this tin-containing iron base powder as a sintering material, there can be obtained sintered products having a high density and excellent magnetic properties.
