摘要：

We report a significant decrease in the temperature coefficient of the dielectric constant (TCK) for polycrystalline ceramics of barium-strontium-titanate through admixture with tetragonal bronze-type barium strontium niobate. For Ba0.5Sr0.5TiO3 ceramics, a 10% admixture of the niobate decreases TCK by a factor of 2.5 at 10 MHz, with negligible degradation of the dielectric loss; a 37.5% admixture decreases TCK by a factor of more than 100. Dielectric constants for the mixtures are in the range of 200-500. (C) 1995 American Institute of Physics.
