Abstract
An ultra-broad temperature stable (−55 to 300°C, ΔC/C20°C<±15%) dielectric material was successfully prepared in this study. The effects of glass content on the phase structure, dielectric and electric properties of the ceramics were investigated. The glass plays a decisive role in achieving the ultra-broad temperature stability and enhancing dielectric constant. The maximum change rate of capacitance is reduced from 68% to only 10%. The 5.0wt% glass-doped sample exhibits excellent dielectric properties (εr=1917, tanδ<1.78%, ΔC/C20°C<±10%), and it has high withstand voltage and high insulation resistivity. These results indicate that this material is a promising candidate for ultra-broad temperature multilayer ceramic capacitors.
