Composition for forming dielectric ceramic and dielectric ceramic material
Provided are: a composition for forming a dielectric ceramic; and a dielectric ceramic material obtained by firing the composition. The composition includes a perovskite-type composite oxide represented by (Ba1-xCax) mTiO3 (0 < = x < = 0.250, 0.980 < = m < = 1.020) as a main component, and an M compound (M is at least one of Ba and Ca), an Mg compound, an Mn compound, an Ma compound (Ma is at least one of V, Nb and Ta), an Mb compound (Mb is at least one of Y, Tb, Dy, Ho, Er, Tm and Yb), and an Mc compound (Mc is at least one of Si and Ge) as additive components. The contents of the added components are 0.01 to 5.00 mol (in terms of MO), 0.20 to 2.00 mol (in terms of MgO), 0.05 to 0.40 mol (in terms of MnO), 0.02 to 0.20 mol (in terms of Ma2O5), 0.20 to 3.00 mol (in terms of Mb2O3), 0.18 to 3.50 mol (in terms of McO2), more than 0.010 of Ma2O5/Mb2O3, and more than 0.90 of McO2/Mb2O3 relative to 100 mol of the perovskite type composite oxide.
提供电介质陶瓷形成用组合物及将该组合物烧制得到的电介质陶瓷材料。该组合物包含作为主成分的(Ba1－xCax)mTiO3(0≤x≤0.250、0.980≤m≤1.020)表示的钙钛矿型复合氧化物和作为添加成分的M化合物(M为Ba及Ca中至少1种)、Mg化合物、Mn化合物、Ma化合物(Ma为V、Nb及Ta中至少1种)、Mb化合物(Mb为Y、Tb、Dy、Ho、Er、Tm及Yb中至少1种)和Mc化合物(Mc为Si及Ge中至少1种)，添加成分含量是相对于100mol钙钛矿型复合氧化物以MO计0.01～5.00mol、以MgO计0.20～2.00mol、以MnO计0.05～0.40mol、以Ma2O5计0.02～0.20mol、以Mb2O3计0.20～3.00mol、以McO2计0.18～3.50mol，Ma2O5/Mb2O3为0.010以上，McO2/Mb2O3为0.90以上。
