摘要：
PURPOSE:To obtain high strength porous ceramics constituting of three- dimensionally interlaced crystals and having continuous spaces at the inside of firing a molded body of acicular mullite powder extracted from a fired clay mineral. CONSTITUTION:A clay mineral contg. silicon dioxide and aluminum oxide as principal components is fired and a glass component is leached out with an acid and alkali to obtain acicular mullite powder. This mullite powder or a mixture of this powder or a mixture of this powder with an org. material is molded and this molded body is fired to obtain porous ceramics having freely controlled characteristics or pores.
