Abstract

The purpose of this study is to make a superplasticity ceramic foam with several isolated closed pores. Three mol percent of yttria stabilized zirconia (3YSZ) was used as foam matrix and β -SiC as foam agent. Two kinds of powder slurries based on methyl cellulose aqueous solution were first prepared. Using the 3YSZ slurry, green sheet was fabricated using a glass bar. After dried, patterning of SiC slurry was conducted on the 3YSZ sheet through a copper mask. Three patterned sheets were cut and buried in a 3YSZ powder compacts. Through the heat treatment at the sintering temperature, a ceramic foam containing several isolated closed pores derived from the SiC pattern was successfully fabricated.
