  • Patent number: 10343930
    Abstract: The present invention relates to the dielectric composition including barium titanate, strontium titanate, titanium oxide and bismuth oxide. In case when the content of barium titanate, converted to BaTiO3, is a mol %, the content of strontium titanate, converted to SrTiO3, is b mol %, the content of titanium oxide and bismuth oxide, converted to Bi2Ti3O9, is c mol %, and a+b+c=100, a, b and c are values within a scope surrounded by the following four points, i.e. point A, point B, point C and point D in a three-dimensional phase diagram. Point A: (a, b, c)=(52.1, 40.0, 7.9); point B: (a, b, c)=(86.5, 5.6, 7.9); point C: (a, b, c)=(91.0, 5.6, 3.4); point D: (a, b, c)=(56.6, 40.0, 3.4).
    Type: Grant
