Phase equilibrium of the La+Ca+Mn+O system at 9003C in atmosphere was examined and illustrated in the form of a phase diagram. La 1؊x Ca x MnO 3 forms a solid solution with two distinct perovskite structures (R3 c and Pnma). A new compound La 2 Ca 2 MnO 7 , identi5ed in the phase diagram, crystalliz
