Abstract


Phase equilibria in the PbOx-CaO system at oxygen partial pressures of 1.01 x 105 and 1.01 x 103 Pa were experimentally investigated. The temperatures of the eutectic reaction between PbO and PbCa2O4 and of the peritectic melting of PbCa2O4 were measured via differential thermal analysis at five oxygen partial pressures. The phase transition in air between PbO and Pb3O4 was not affected by the coexistence of PbCa2O4.
