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.
