Abstract

Crystalline powders of pure cordierite are difficult to sinter because of the very narrow sintering range within about 50ŒC of its incongruent melting point of 1468ŒC. Furthermore, high strength cordierite-type glass ceramics have been made by inducing spinel to crystallize. In order to make dense cordierite-type ceramics having high strength at relatively low temperatures, liquid phase sintering can be used.
