Preparation and Electrical Properties of Some Ceramic Materials at Microwave Frequencies.

Abstract

The need for high-dielectric constant, low-loss, temperature-stable ceramic materials for microwave-device application has given impetus to the study of various titanate and oxide mixtures. In the course of this research we have developed a material which has a temperature frequency coefficient of 530 ppm/deg C and a dielectric constant of 106, comparable to the American Lava T-96 Ceramic, but has a higher dielectric constant. Methods for mixing, firing, and aging of ceramic materials, as well as microwave measurement techniques, are presented and results are given in graphic form and tables. These results may be valuable to workers wishing to pursue the development of zero temperature coefficient materials further. (Author)
