SINTERED COMPACT AND METHOD FOR PRODUCING THE SAME
PROBLEM TO BE SOLVED: To provide a material capable of continuously, safely eluting divalent iron ions at a high concentration in the environment over a long period without generating a new environmental load in seawater.SOLUTION: Provided is a sintered compact 10 being a porous sintered compact comprising a plurality of iron grains 1 and a carbonaceous matter 3. In the sintered compact 10, a plurality of the iron grains 1 are stabilized by the carbonaceous matter 3. The carbonaceous matter 3 functions as a structure of carrying the iron grains 1, and further forms a local battery by contact with the iron grain 1. In the sintered compact 10, the ratio between the iron grains 1 and the carbonaceous matter 3 is 95:5 to 5:95 by the weight ratio between the iron element and the carbon element (iron element:carbon element), apparent specific gravity is 1.1 to 4.0, open porosity is 20 to 70%, and a collapse load is 50 N or more.SELECTED DRAWING: Figure 1
【課題】海水中で新たな環境負荷を発生させることなく、２価鉄イオンを高濃度、かつ長期に渡って安定的に環境中に溶出させ続けることが可能な材料を提供する。【解決手段】焼結体１０は、複数の鉄粒子１と炭素質物３とを含有する多孔質な焼結体である。焼結体１０において、複数の鉄粒子１は、炭素質物３によって固定化されている。炭素質物３は、鉄粒子１を担持する構造体として機能するとともに、鉄粒子１との接触によって局部電池を形成する。焼結体１０は、鉄粒子１と炭素質物３との比率が、鉄元素と炭素元素の重量比（鉄元素：炭素元素）で９５：５〜５：９５であり、見かけ比重が１．１〜４．０であり、開気孔率が２０〜７０％であり、圧壊荷重が５０Ｎ以上である。【選択図】図１
