Suvorov, A. Nikiforov] Conclusions: We studied the kinetics of solid phase synthesis of lanthanum chromite and solid solutions based on it in the system La2O3-Cr2O3-CaO-O2. A relationship was obtained between the degree of conversion in the system and the synthesis temperature, the exposure time, and the CaO concentration. The synthesis of pure LaCrO3 from oxides is quantitatively complete at 1695 K and with an exposure time of 2 h. The presence in the original mixture of CaCO3 leads to the formation, in addition to LaCrO3, of the compound β-Ca(CrO2)2, and then with increase in the synthesis time to 10 h, at 1695 K, to the formation of solid solutions of the type La1−xCaxCrO3 (x≤0.25). We determined the constants for the crystal lattices for the synthesized solid solutions. The technological parameters determined for the solid-phase synthesis can be used in work on the preparation of resistor elements made of lanthanum chromite.
