PRODUCTION OF POROUS METAL

摘要

PURPOSE: A process for preparing a porous metal by removing an air layer present between raw material powder in advance in the manufacture of a porous metal by heating and pressing a mixture of powdery salt and metal powder at high temperature is provided, which improves finished product characteristics and increases the productivity of a thin plate. CONSTITUTION: In a process for the manufacture of a porous metal by heating and pressing a mixture of powdery salt and metal powder at high temperature and eluting salt from the obtained molded product, air pressure is maintained less than atmospheric pressure by removing an air layer present between raw material powder in advance.
