In this research, the initial powders (talc, kaolin, and synthetic alumina) were mixed in a planetary ball mill using different amounts of TiO₂ and tialite. The mixtures were sintered at 1250, 1300, and 1350 &deg;C for 3 h. X-ray diffractometry and fluorescence, thermal analysis, microstructural observation, density, and cold compressive strength (CCS) were used to evaluate the sintered samples. Phase analysis revealed the presence of the cordierite phase along with small amounts of spinel. With increasing sintering temperature and titania addition, the amount of spinel decreased and the amount of cordierite phase increased. The real density increased with increasing titania additive content, but at higher titania contents, microcracks were observed in the SEM micrographs.
