ABSTRACT:
A process for producing dense-sintered cordierite bodies and zirconium dioxide-reinforced cordierite bodies with a maximum of 50% by weight of ZrO.sub.2 is described, wherein a powder of cordierite particles of stoichiometric composition and, if appropriate, ZrO.sub.2 of a particle size of less than 3 .mu.m is heated at temperatures above 800.degree. C. at a rate of temperature rise of less than 5.degree. C. per minute. Virtually pore-free sintered bodies having outstanding mechanical properties can be produced by the process.
