✦ Synopsis

Composite materials with 85 to 65 wt% cordierite and 15 to 35 wt% Zr02 were prepared from co-precipitated cordierite powder, and their densification behaviour, microstructure, mechanical strength, fracture toughness, thermal expansion and thermal shock resistance were studied. Addition of Zr02 to pure cordierite lowered the sintering temperature needed to obtain a dense sintered body. The fracture strength could be increased from 110 to 260 MPa and the thermal shock resistance from 350 to 500~ by dispersing 15 wt% Zr02 particles in the cordierite matrix.
