Abstract

The performance of calcined MnO₂-ZrO₂-SiO₂ (MZS) compositions as sintering aids for a non-reducible (Ca_0.7Sr_0.3O)_1.03(Ti_0.1Zr_0.9)O₂ (CSTZ) dielectric material has been investigated at the sintering temperature of 1230-1250 °C in a reducing atmosphere. The sintered body yielded the (Ca_0.7Sr_0.3O)_1.03(Ti_0.1Zr_0.9)O₂ dielectric phase with traces of calcium zirconates. When 2.5 wt% of MZS (0.55MnO₂-0.05ZrO₂-0.40SiO₂) was added and sintered at 1250 °C, the specimen demonstrated an apparent density of 4.95 g/cm³, a dielectric constant of 32.4, a dielectric loss of 0.0003, an insulation resistance of 2×10¹¹ Ω, and temperature coefficients of capacitance of -12 ppm at -55 °C and -9 ppm at 125 °C (with respect to the 25 °C standard). These dielectric properties satisfy the C0G characteristics, and thus the CSTZ dielectric material with the MZS sintering aid can be used for multilayer capacitors with high temperature reliability.
