DEVELOPPEMENT D'UN FOUR MICRO-ONDES MONOMODE ET FRITTAGE DE POUDRES CERAMIQUE ET METALLIQUE

Abstract : A single-mode microwave cavity was developed to study the sintering of ceramic and metallic powders. In this TE10p cavity, the electromagnetic pattern is controlled and the materials can be heated up under either predominant electric or magnetic field. Samples can be microwave-sintered directly or with a cylindrical SiC susceptor. The temperature was measured by an infrared camera. A new microwave heating procedure was proposed to control a thermal cycle. Comparatives studies between microwave and conventional sintering processes were achieved on ceramic and metallic powders. Microwave sintering of yttria-doped zirconia at 25°C/min heating rate led to a shift of the densification curve, an enhancement of the kinetics of densification during the initial and intermediate stages and a restricted grain growth. A submicronic nickel powder can be only sintered by plasma-induced heating under predominant electric field.
