Heat Engineering

Refractory lanthanum chromite-dielectric composites are synthesized. X-ray phase analysis of composites after high-temperature treatment indicate compatibility of lanthanum chromite with such oxides as Y2O3, LaYO3, MgO, TiO2, LaAlO3, LaAl11O18, La2TiO5, La2Ti2O7, La4Ti9O24, La2SiO5, La2Si2O7. Intensification of LaCrO3 sintering in the presence of dielectric additions coexisting with it is demonstrated. The effect of the form of dielectric on the sintering capacity of lanthanum chromite alloyed with calcium and without it is demonstrated.
