Microwave Sintering Behavior and Electrical Properties of BaTiO$_3$ Ceramics
ABSTRACT
The microwave sintered BaTiO3 samples were obtained by using the microwave sintering device which can precisely control the sintering temperature and the sinter time by using IR optical thermometer and PID temperature controller. During microwave sintering the internal temperature of samples were mesur-ed by the optical fiber thermometer to compare the sintering behaviors between microwave- and con-ventionally sintered ones. The former showed the faster rate of grain growth with sintering time and the larger grain size than the latter. Also they showed the similar pattern of dielectric properties with tem-perature changes from 2$0^{circ}C$ to 16$0^{circ}C$
Key words: Microwave sintering, BaTiO$_3$ ceramics, physical & dielectric properties
