Pagination or Media Count:
Microwave sintering of zirconia - 8 mol yttria in a 2.45 GHz microwave furnace is described. The nominal sintering temperature of the zirconia is 1375 deg C in the conventional furnace, but is only 1200 deg C in the microwave furnace. Difficulties were encountered in producing uncracked sintered parts in the microwave furnace because of the low thermal conductivity and rapid change in dielectric properties of the zirconia. An indirect heating method was developed to alleviate these problems and to make heating more uniform.
