Ceramic material used in the electrical industry e.g. for producing dielectric resonators contains two different components having a perovskite structure containing silver on the A sites and niobium and tantalum on the B sites

摘要

Ceramic material contains two different components in phases different from each other. The components have a perovskite structure containing silver on the A sites and niobium and tantalum on the B sites. The composition of the components is selected so that the temperature coefficients of their dielectric constants are different in a temperature interval. Preferred Features: The material is produced by sintering a mixture of particles of component A with particles of component B using H3BO3 or V2O5 as sintering aid.
