发明名称 Method for making high K PLZT ceramic capacitor
摘要 A powder blend consisting essentially of precursors of a single antiferroelectric compound of lead-barium-lanthanum-zirconate titanate doped with silver, includes at least 0.7 mole percent bismuth permitting a near-full reaction to be achieved at calcining in the low temperature range of 1000 DEG C. to 1130 DEG C. A body is formed of the pulverized calcined material, which body is then sintered in a closed container at 1100 DEG C. Residual PbO remains in the body rendering it conductive. The body is annealed in open atmosphere at 950 DEG C. to drive out the free PbO providing an excellent dielectric having an unusual combination of high K and low TCC.
