Abstract

Microwave processing is generally believed to be method of highly efficient production. The two different sintering process (microwave and conventional) for Al₂O₃-ZrO₂ composite produce different phase transformation, microwave sintering promoted the formation of t-ZrO ₂ at 1300°C and 1400°C, while this phase forms in sample with conventional sintering at 1400°C. Microwave sintering results in higher densities, flexural and compressive strength compared to conventional sintering. The porosity of sintered Al₂O₃- ZrO₂ composite increased with increasing of starting ZrSiO₄ particle size. Furthermore by microwave sintering, the microstructure of composites show more dense and uniform grain growth.
