Outline of Final Research Achievements |
Previous studies by the authors have been intended to develop novel sintering additives that can allow alumina to be sintered at a low temperature with a small quantity of additive. Then, low temperature sintered alumina, which has high density and thermal conductivity at a firing temperature of 900 degrees Celsius, has been invented. In this study, co-firing of the above material with Ag electrodes was examined. As a result, it was successful to inhibit reaction loss of Ag electrodes by control of chemical compositions of above additives. Thus, an elementary technology of LTCC (Low Temperature Co-fired Ceramics) laminated devices having unprecedented high thermal conductivity could be constructed. Also an effect of firing atmosphere on sintering performance of above material was investigated, and finally a guideline for further improvement of sintering ability was obtained.
