Abstract

Relaxor ferroelectric ceramics with the composition ofxPb(Mg1/3Nb2/3)O3-yPb(Zn1/3Nb2/3)O3-zPbTiO3 was fast sintered in a 2.45 GHz microwave system. Microwave-sintered samples illustrate more rapid densification and much smaller grain size microstructure than conventional sintered samples. Also the microwave processing significantly increases the dielectric strength and flexural strength of the relaxor so that its strength becomes comparable with modified BaTiO3, and could obtain comparable dielectric properties in comparison with conventional sintering process. Microwave processing has many advantages for sintering of relaxor ferroelectric ceramics used as multilayer capacitors.
