In the past decades, low temperature cofired ceramics (LTCC) substrate and related packaging technology have been extensively studied for the miniaturization of the electronic devices. In this study, a new LTCC ceramics consisting of CaO-Al2O3-SiO2-B2O3-MgO (MLS-22) and Al2O3 were fabricated and their sintering mechanism, mechanical and thermal properties were investigated. When 20wt% Al2O3 was added to MLS-22, the LTCC ceramics was well sintered at 900oC for 1 h with a high relative density of 93% of theoretical density. They also showed a high bending strength and a good thermal conductivity of 322.9MPa and 3.75 W/mk, respectively, indicating that these LTCC ceramics can be used to the substrate for supercapacitors. In addition, the detailed investigation on the variation of microstructure with respect to the sintering condition was studied. Moreover, the relation between the microstructure and the mechanical and thermal properties of the specimens were discussed in this work.
