PURPOSE:To provide a low-temp. sintering ceramic compsn. for a multilayered substrate which can be sintered at rather low temp. and has small coefft. of thermal expansion, small dielectric const., and that the changing rate of capacity on temp. can be easily controlled. CONSTITUTION:This low-temp. sintering ceramic compsn. for a multilayered substrate consists of 100 pts.wt. of the main component and 20 pts.wt. of TiO2 as subcomponent added thereto. The main component consists of 40-85wt.% cordierite, 10-40wt.% B2O3 and 5-50wt.% of SiO2. |
