Abstract

Results are given for a study of the effect of LiF, ZnO, and Ce2O3 modifying additions on synthesis and properties of cordierite-mullite ceramic from Kazakhstan resources. It is established that addition of LiF, ZnO, and Ce2O3 facilitates activation of synthesis for cordierite-mullite ceramic based on natural raw material. Addition of LiF reduces the temperature for the start of eutectic melt development, facilitating intensification of cordierite formation, and ZnO and Ce2O3 act by a solid-phase mechanism. Introduction of LiF, ZnO, and Ce2O3 into the composition of cordierite-mullite ceramic in an amount of 0.5 – 2.0% makes it possible to reduce its firing temperature and increase density, strength, and chemical and thermal stability.
