DIELECTRIC CERAMIC CAPACITOR COMPRISING NON-REDUCIBLE DIELECTRIC

摘要

A dielectric ceramic, and capacitor with the ceramic, wherein the ceramic has: about 94 - 99.9 wt% a first component defined by Formula (1), wherein: x is no more than about 0.6; and y is no more than about 0.1; and m is at least about 0.85 to no more than about 1.15; and about 0.1 - 5 wt% a secondary component defined by Formula (2), wherein: a, b and c are selected to lie within the region defined by points A(a=15, b=0, c=85), B(a=70, b=0, c=30), C(a=0, b=70, c=30) and D(a=0, b=15, c=85) of a ternary diagram wherein a is mole percent SiO2; b is mole percent aB<SUB>2</SUB>O<SUB>3</SUB>-(I -a)Li<SUB>2</SUB>O; and c is mole percent AO and a+b+c=100 including the lines BC, CD and AD but excluding the line AB; a is O to 1; A is selected from Mg, Ca, Sr, Ba or a combination thereof; and 0 - 2 wt% MnO<SUB>2</SUB>.
