METHOD FOR MANUFACTURING METAL- OR CERAMIC-CONTAINING FOAMED SINTERED BODY

摘要

PROBLEM TO BE SOLVED: To provide an extremely industrially advantageous method for manufacturing a bulk closed-cell-type metal- or ceramic-containing foamed sintered body of high degree of foaming and high porosity by which the foamed sintered body can be manufactured even if hard-to-work materials, such as ceramics, as well as a wide range of metals are used as a raw material. SOLUTION: A mixture containing a metal or ceramic powder, a water-soluble high polymer having gelation property and a foaming agent is gelatinized, foamed and then sintered.
