Ceramics and method of preparing the same

Ceramics containing a diopside crystal phase and a cordierite phase, the remainder being a glass phase and/or other ceramic crystal phases, and having an open porosity of not larger than 1%. The ceramics is obtained by firing at from 800 to 1050° C., and exhibits a dielectric constant of not larger...

description Ceramics containing a diopside crystal phase and a cordierite phase, the remainder being a glass phase and/or other ceramic crystal phases, and having an open porosity of not larger than 1%. The ceramics is obtained by firing at from 800 to 1050° C., and exhibits a dielectric constant of not larger than 7 and a small dielectric loss in a high-frequency region, a ceramic strength of not smaller than 250 MPa, and a coefficient of thermal expansion close to those of the chips such as of Si and Ga-As and of the printed board.
