CERAMIC MATERIAL BASED ON ZINC-SUBSTITUTED BISMUTH NIOBATE Russian patent published in 2001 - IPC

Abstract RU 2167842 C1

FIELD: ceramics. SUBSTANCE: invention can be used in production of multilayer high-frequency heat-resistant ceramic condensers with electrodes based on alloy containing Ag and Pd and also in production of layered microwave filters. Invention aims at creating ceramic material with low sintering temperature and which would have dielectric constant optimal for manufacturing wide variety of products and high heat resistance. For that, zinc-substituted bismuth niobate with pyrochlore structure is preliminarily synthesized, after which synthesis of zinc-substituted bismuth niobate with structure of columbite is performed. Thus synthesized components are mixed and mixture is completed with wet ground glass. The total is then dried. Addition of niobate within wide concentration range extends series of new materials with wide range of heat-resistant and temperature-compensating groups, which provides possibility of manufacturing wide variety of ceramic condensers, including those belonging to most promising group with electrodes containing less than 30% palladium. EFFECT: reduced expenses due to lower use of palladium and extended variety of products. 2 cl, 2 tbl
