| Abstract |
The effect of A/B moi ratios and sintering temperatures on dielectric properties and microstructure of (Ba_{0.93}Ca_{0.07})_m(Ti_{0.82}Zr_{0.18})O_3 ceramics were investigated. The dielectric constant decreased with increasing the A/B mol ratio. However, the dielectric loss is improved. As the dielectric properties of A/B mol ratio with m = 1.009 at sintered temperature 1260°C, we obtained dielectric constant 12,800, dielectric loss 3.5 % and Y5V temperature characteristics. Highly reliable Ni-MLCCs, 1.6mm(length){×}0.8mm(width){×}0.8mm(height) with capacitance of 1.23 μF and 야ssipation loss of 5.2 % were obtained employing dielectric material composed of (Ba_{0.93}Ca_{0.07})_{1.009}(Ti_{0.82}Zr_{0.18})O_3 - MnO_2 0.2wt %-Y_2O_3 0.18wt %, - SO_2 0.15wt %-(Ba_{0.4}Ca_{0.6})SiO_3 1wt %. |
