摘要： The present invention relates to a mixed powder for powder metallurgy containing an iron-base powder and a carbon supply component, in which the carbon supply component contains a graphite powder and a carbon black, and in which a mixing ratio of the graphite powder to the carbon black is in the range of 25 to 85 parts by weight to 75 to 15 parts by weight; and a mixed powder for powder metallurgy containing an iron-base powder and a carbon supply component, in which the carbon supply component contains, as a main component, a carbon black having a dibutyl phthalate absorption of 60 mL/100 g or less and a nitrogen absorption specific surface area of 50 m2/g or less.The mixed powder for powder metallurgy of the invention is less in the dust generation and segregation of the carbon supply component. Additionally, when the mixed powder for powder metallurgy of the invention is used, a green compact and a sintered body excellent in the mechanical property can be produced.

摘要： An agent for removing organic chlorine compounds which is composed of (A) an iron powder having a BET specific surface area of from 0.010 to 3 m2/g, and (B1) a powder of at least one species of metal selected from the group VIII elements (excluding Fe) in the periodic table, and/or (B2) a porous substance in powder form supporting said metal. If the agent is composed of (A) and (B1), the amount of (B1) is 0.01 to 10 parts by mass for 100 parts by mass of (A). If the agent is composed of (A) and (B2), the amount of (B2) is 0.0001 to 10 parts by mass for 100 parts by mass of (A). This agent is capable of removing organic chlorine compounds efficiently.
摘要翻译：一种除去有机氯化合物的试剂，其由（A）BET比表面积为0.010〜3m 2 / g的铁粉和（B1）至少一种选自周期表中VIII族元素（不包括Fe）的金属和/或（B2）支撑所述金属的粉末形式的多孔物质。如果试剂由（A）和（B1）组成，则（B1）的量为（A）100质量份时为0.01〜10质量份。如果试剂由（A）和（B2）组成，则对（100）（A）100质量份，（B2）的量为0.0001〜10质量份。该试剂能有效去除有机氯化合物。

摘要： The invention provides an iron-based cleaning powder capable of efficiently decomposing organic halides. The iron-based cleaning powder is made of iron alloy powder or iron powder produced with an atomization process. The iron alloy powder passes a 300 &mgr;m-mesh sieve at a proportion of not less than 90% and has an H2-reduction mass loss of 0.1 to 0.8% when it contains 0.3 to 1.1% of Mn. When the iron alloy powder contains 0.2 to 12% of Ni, it has an H2-reduction mass loss of 0.1 to 1.0%. The iron powder is used as mixed powder or partially alloyed powder together with Ni-containing powder. The iron powder passes a 300 &mgr;m-mesh sieve at a proportion of not less than 90% and has an H2-reduction mass loss of 0.1 to 1.0%. The Ni-containing powder has a Ni content of not less than 40% and passes a 45 &mgr;m-mesh sieve at a proportion of not less than 90%. The iron alloy powder and the iron powder have a martensite structure or a tempered martensite structure.
