The influence of MoO3 on the process of cordierite ceramics preparation, 2MgO-2Al2O3-5SiO2 (MAS) was researched by sintering followed binary systems: MgO/MoO3 (sintered at 850 ºC and 1000 ºC), Al2O3/Bi2O3 and SiO2/Bi2O3 (sintered at 850 ºC and 1000 ºC). Composition of these systems was 80 % of oxide and 20 % MoO3. The effects of sintering, the composition and morphology were followed by x-ray diffraction, scanning electron microscopy and EDS analysis. It has been found that MoO3, beside liquid phase, forms intermediary unstable compounds with MgO and Al2O3. The following research is planned to investigate the effect of 5 % mass of MoO3 on the electrical properties of cordierite ceramics.
