摘要：
A process for producing porous cast iron, wherein cast iron having flake graphite structure is subjected to heat treatment in a high temperature gas atmosphere in which the iron component of the cast iron base is not subjected to oxidation and on the other hand the flake graphite is subjected to oxidation, whereby the flake graphite disappears from the cast iron to form pores therein.
