Latest Patents

Hitoshi Sakuma holds a patent for an iron-based cleaning powder. This invention provides a solution capable of efficiently decomposing organic halides. The cleaning powder is composed of iron alloy powder or iron powder produced through an atomization process. The iron alloy powder is designed to pass a 300 µm-mesh sieve at a proportion of not less than 90%. It exhibits an H-reduction mass loss of 0.1 to 0.8% when containing 0.3 to 1.1% of manganese (Mn). Additionally, when the iron alloy powder contains 0.2 to 12% of nickel (Ni), it has an H-reduction mass loss of 0.1 to 1.0%. The iron powder can be used as a mixed or partially alloyed powder in conjunction with Ni-containing powder, which has a Ni content of not less than 40% and also passes a 45 µm-mesh sieve at a proportion of not less than 90%. Both the iron alloy powder and the iron powder possess a martensite structure or a tempered martensite structure.
