| Outline of Final Research Achievements |
Indialite powder with high quality factor (Q), low dielectric constants, and 1 micron diameter has been fabricated. And Low Temperature Co-fired Ceramics (LTCC) materials based the fine indialite powder have been researched. The first physical year: Indialite powder with 1 micron has been fabricated from glass with same composition of indialite, because indialite is intermediate phase during crystallized from glass to cordierite which is a polymorph of indialite. The glass was melted, crashed to coarse-grained particles and crystallized, and grained into fine particles by planetary ball milling. The second physical year: 7 pieces sintering aides were applied to LTCC sintering at around 900 oC, and selected some candidates for LTCC sintering aides. The third physical year: LTCC materials with good dielectric properties were developed focusing eutectic temperature (lowest temperature on the system) of B2O3-CuO and Bi2O3-CuO systems.
