Ni BASED POWDER HAVING EXCELLENT ANTIBACTERIAL AND MOLD PREVENTION PROPERTIES, PRODUCTION METHOD THEREFOR, AND MATERIAL RESIN AND MEMBER CONTAINING THE SAME Ni BASED POWDER AND HAVING EXCELLENT ANTIBACTERIAL AND ANTIFUNGAL PROPERTIES

摘要

PROBLEM TO BE SOLVED: To produce metal powder which stably exhibits higher antibacterial and antifungal properties by further increasing the antibacterial and antifungal of Ni based powder containing hydrogen. SOLUTION: The Ni based powder having excellent antibacterial and antifungal properties is obtained by sticking a P and/or S-containing compound to the surface of Ni or Ni alloy powder in which the content of Ni in an Ni or Ni alloy part is >=20 mass%, and the content of hydrogen is 1 to 10,000 ppm. The sticking quantity of the P and/or S-containing compound is <=1% in terms of a ratio occupied in the whole of the powder, and the total content of P and/or S in the compounds is >=0.001% in terms of a ratio occupied in the whole of the powder.
