METHOD FOR STABILIZING SINTER FOAM AND FOR PRODUCING OPEN-CELLED SINTER FOAM PARTS

摘要

In a process for stabilizing a foamed starting slip material, the starting slip material which is foamed comprises the following constituents:a. inorganic sinterable material,b. a source of blowing gas,c. a framework former which forms a framework when the pH of the starting slip material is changed,d. pH control material,e. liquid,f. if desired, one or more of the following materials:dispersantbinderviscosity modifier, andthe pH of the starting slip material is changed to initiate or accelerate the formation of the framework from the framework former.
