Additives for low temperature sintering of mullite ceramics were investigated for matching Mo-Cu conducting paste with that ceramics at 1,400°C. SiO2, MgO and Y2O3 were chosen as the additives for low temperature sintering, and the amounts of those additives were varied with sintering temperature of 1,400°C to 1,500°C. With additives of 1.0 wt% of SiO2, 1.0 wt% of MgO, and 1.5 wt% of Y 2O3, the densest sintered body of 3.12 g/cm3 was obtained at 1,400°C in reducing atmosphere. The flexural strength of that was 325 MPa and the CTE (Coefficient of thermal expansion) was 4.33 ppm/°C.
