PREPARATION OF SR(ZR, TI)O3 CERAMICS AND THEIR DIELECTRIC-PROPERTIES AT MICROWAVE-FREQUENCIES

Powder of the dielectric ceramic Sr(Zr, Ti)O3 Was prepared by a new chemical method using TiO2 powder. The obtained fine and well-dispersed powder had good sinterability. The microscopic compositional uniformity in the sintered body was estimated by WDX, and the dielectric properties were measured at 6 GHz and 1 MHz. The samples prepared by the chamical method had excellent uniformity and a Q value (1/tan delta) 2.5 times that of the samples prepared by the conventional method.
