Title:
METHOD FOR PRODUCING SINTERED METALLIC FILTER
Document Type and Number:
Japanese Patent JP2008069416
Kind Code:
A
Abstract:
To mass-produce a sintered metallic filter at a low cost while the flow rate of a treatable fluid is increased by increasing porosity.
A powdery mixture 3 obtained by admixing raw material powder 1 with resin powder 2 decomposable at a temperature lower than the sintering temperature of the raw material 1 is subjected to compression molding. The green compact 4 obtained by the compression molding is heated to the decomposition temperature of the resin powder 2, and the resin powder 2 is vaporized away. Thereafter, the same is heated to the sintering temperature of the raw material powder 1, and the green compact 4' is sintered, so as to obtain the sintered metallic filter.
