Temperature stable dielectric

摘要

Barium titanate temperature stable dielectric compositions are disclosed containing magnesium oxide, silicon dioxide, germanium oxide and optionally an oxide or carbonate of barium, calcium or strontium which can be used to produce multilayer ceramic capacitors with nickel or nickel alloy electrode that have a variation of capacitance with temperature of less than +/-10% over the range -55 DEG C. to +125 DEG C. compared with the value of the capacitance at 25 DEG C., or to produce multilayer ceramic capacitors with noble metal inner electrodes that have a variation of capacitance with temperature of less than +/-15% over the range 55 DEG to +125 DEG C. compared with the value at 25 DEG C., and which does not contain any second phases after sintering.
