摘要:
A decrease in the temperature coefficient of the dielectric constant (TCK) for polycrystalline ceramics of Barium Strontium Titanate (BST) through admixture with tetragonal bronze type Barium Strontium Niobate (BSN) has been found. For Ba.sub.0.5 Sr.sub.0.5 TiO.sub.3 ceramics, a 10% admixture of BSN decreases TCK by a factor of 2.5 at 10 MHz, with negligible degradation of the dielectric loss. A 37.5% admixture of BSN decreases TCK by a factor of more than 100. Dielectric constants for the mixtures are in the range of 200-500.
