Sintering of a crystalline cordierite/ZrO2 composite

Abstract

Dilatometry was used to investigate the sintering of a composite material with 70 wt% crystalline cordierite and 30 wt% 3Y-TZP. Using a precision digital dilatometer, results for constant rate of heating sintering and rate-controlled sintering are compared. In both cases dense bodies with homogeneous distributions of both components are obtained. Reactions between the two components are observed only in the case of sintering with constant rate of heating and low heating rates.
