    摘要： Disclosed is a dielectric ceramic having crystal grains mainly composed of barium titanate and an intergranular phase formed among the crystal grains. The dielectric ceramic contains certain amounts of manganese and at least one rare earth element (RE) selected from magnesium, gadolinium, terbium, dysprosium, holmium and erbium, in terms of oxides, per 1 mole of barium constituting the barium titanate. The dielectric ceramic also contains a certain amount of yttrium in terms of oxides, per 100 parts by mass of the barium titanate. The crystal grains have an average grain size of 0.05-0.2 μm. By using the dielectric ceramic as a dielectric layer, there can be obtained a capacitor having high capacity and stable capacitance temperature characteristics.

    摘要： A pyroelectric ceramic composition contains a compound represented by (Pb1−xCax)(1+a){(Ni1/3Nb2/3)yTi(1−y)}O3 (wherein x, y, and a satisfy 0.20≦x≦0.27, 0.01≦y≦0.06, and 0.001≦a≦0.02, respectively) as a main component and 0.3 to 2.5 mol of Mn per 100 mol of the main component. The amount of segregates containing Ni, Ti, and Mn is 1.0 vol % or less (including 0 vol %) of a fired sinter. A pyroelectric ceramic composition that has an adequately low insulation resistance and a high Curie temperature while achieving satisfactory pyroelectric properties is realized. Since the composition has a high Curie temperature, a thin, small pyroelectric element that withstands a reflow process can be obtained. Since the composition has a low insulation resistance, an infrared detector incorporating a pyroelectric element composed of the composition does not require a load resistance to be provided in parallel to the pyroelectric element and size reduction is possible.

    摘要： In a varistor element, Ca exists in the grain interior of grains consisting primarily of ZnO in a varistor element body and Ca also exists in a grain boundary. In this crystal structure Ca replaces oxygen defects in the grain interior of grains consisting primarily of ZnO, in the varistor element body to make the ceramic structure denser Such crystal structure also decreases a ratio of an element tending to degrade the stability of the temperature characteristic of the varistor element, e.g., Si as a firing aid, in the grain boundary between grains. As a result, the varistor element has a stable temperature characteristic, which can decrease change in capacitance and tan δ (thermal conversion factor of resistance) against change in temperature.

    摘要： An electrostatic chuck that is a member for a semiconductor-manufacturing apparatus contains an yttrium oxide material containing first inorganic particles and second inorganic particles. The first inorganic particles form solid solutions in yttrium oxide, can be precipitated from yttrium oxide, and are present in grains of yttrium oxide. The second inorganic particles can form solid solutions in the first inorganic particles, are unlikely to form any solid solution in yttrium oxide, and are present at boundaries between the yttrium oxide grains. The first inorganic particles contain at least one of ZrO2 and HfO2. The second inorganic particles contain at least one selected from the group consisting of MgO, CaO, SrO, and BaO. The yttrium oxide material is produced in such a manner that solid solution particles are prepared by mixing and firing the first and second inorganic particles and are mixed with yttrium oxide and the mixture is fired.
