    Abstract: A novel ceramic composition having a high relative dielectric constant. A ceramic composition includes a unit cell having at least two crystal structures selected from the group made of a monoclinic crystal, a tetragonal crystal, an orthorhombic crystal, and a rhombohedral crystal, characterized in that when the crystal structures are represented by the symmetry notation according to the Glazer method, namely xn1yn2zn3, n1, n2, and n3 are at least one selected from the group made of + and −, or at least two selected from the group made of 0, +, and −. By using this ceramic composition, a novel ceramic composition having a high relative dielectric constant can be obtained.

    Abstract translation: 具有高相对介电常数的新型陶瓷组合物。 陶瓷组合物包括具有选自由单斜晶体，四方晶体，正交晶体和菱方晶构成的组中的至少两种晶体结构的晶胞，其特征在于，当晶体结构由对称符号表示时 对于Glazer方法，即，xn1yn2zn3，n1，n2和n3是从由+和 - 构成的组中选择的至少一个，或者选自由0，+和 - 组成的组中的至少两个。 通过使用该陶瓷组合物，可以获得具有高相对介电常数的新型陶瓷组合物。
