<p>A dielectric ceramic powder composition comprising barium titanate, magnesium oxide, or a precursor therefor, silicon dioxide or a precursor therefor, germanium dioxide or a precursor therefor and optionally barium, calcium or strontium oxide or carbonate or a precursor therefor, which can be fabricated into multilayer ceramic capacitors with nickel or nickel alloy inner electrodes that have a variation of capacitance with temperature of less than +/-10% over the range -55 DEG C to +125 C compared with the value of the capacitance at 25 C, or which can be fabricated into multilayer ceramic capacitors with noble metal inner electrodes that have a variat:ion of capacitance with temeprature of less than +/-15% over the range -55 DEG C to +125 DEG C compared with the value at 25 DEG C, and which does not contain any second phase after sintering.</p> |
