Abstract

Microwave fast sintering is a technique with a huge potential for the manufacture of a variety of ceramic materials with controlled ceramic microstructures. The objective of the present work was the microwave fast sintering of mullite-cordierite type ceramic composites in a microwave oven and to examine the influence of power and sintering time on the material. In this research, we used an industrial 60%mullite-40%cordierite composite. Samples of the composite were sintered by the conventional and microwave routes, after which they were characterized by X-ray diffraction and scanning electron microscopy, and their density determined. The microwave fast sintering process took less than 10% of the time required for conventional sintering and showed the same sintering mechanisms with power and time controlled. (AU)
