The results of X-ray analysis and microscopical analysis of rapidly quenched samples were used for constructing a pseudobinary phase diagram of the system CaCr₂O₄ - Ca₂Fe₂O₅ in air atmosphere. The peritectic temperature of 1830 ± 10 °C and the eutectic temperature of 1280 ± 10 °C were determined. At contents exceeding 1 mole % CaCr₂O₄ in the system with dicalcium ferrite no solid solutions are formed. |
