The results of studying the effect of modifying additives LiF, ZnO, Ce 2 O 3 on the synthesis and properties of cordieritomullite ceramics from Kazakhstan raw materials are presented. It has been established that the additions of LiF, ZnO, and Ce 2 O 3 contribute to the activation of the synthesis of cordieritomullite ceramics based on natural raw materials. The addition of LiF reduces the temperature of the onset of the appearance of the eutectic melt, which contributes to the intensification of cordierite formation, and ZnO and Ce 2 O 3 act on a solid-phase mechanism. The addition of LiF, ZnO, and Ce 2 O 3 additives to the composition of cordieritommullite ceramics in the amount of 0,5‒2,0 % has made it possible to lower the temperature of its calcination and to increase the density, strength, chemical and thermal stability.
