Summary

Cordierite-ZrO2 composites containing 30 vol % monoclinic (m) or tetragonal (t)-ZrO2 (2 mole % Y2O3) were sintered at temperatures of 1400°C for up to 48 h.

In cordierite-t-ZrO2 composites, rounded particles of ZrO2 develop which grow and assume a regular polyhedral shape. Sintering of cordierite-m-ZrO2 composites for more than 24 h leads to a microstructure containing mainly zircon and spinel The kinetics of microstructure changes and mechanical properties of both types of cordierite-ZnO2-composites are analyzed.
