    摘要: A dielectric ceramic composition comprising forsterite in an amount of 93.0 to 99.0 mol % when calculating in terms of 2MgO.SiO2 and calcium titanate in an amount of 1.0 to 7.0 mol % when calculating in terms of CaTiO3 as main components, and as a subcomponent, aluminum oxide in an amount of 0.2 to 5 mass % when calculating in terms of Al2O3 per 100 mass % of said main components. According to the present invention, a dielectric ceramic composition, capable of having both low permittivity and good frequency-temperature characteristic as well as ensuring high Qf value and further having sufficient mechanical strength, and suitable to use in an antenna, a filter and the like used in the high-frequency region, can be provided. Also, the present invention allows providing a dielectric ceramic composition further having resistance to reduction in addition to all of the above properties.

    摘要: There is provided a dielectric ceramic material in which the firing temperature dependency of the relative dielectric constant can be suppressed and the mechanical strength can be improved. Specifically, there is provided a dielectric ceramic material including: main constituents given by a composition located in the region, in a ternary diagram of ZrO2, SnO2 and TiO2 shown in FIG. 1, bounded by point A, point B, point C, point D, point E and point F; and ZnO: 0.5 to 5 wt %, NiO: 0.1 to 3 wt %, and SiO2: 0.008 to 1.5 wt % in relation to the total weight of the main constituents. The dielectric ceramic material can include Nb2O5: 0.2 wt % or less and K2O: 0.035 wt % or less in relation to the total weight of the main constituents.
