摘要

The standard enthalpy of formation Delta(f)HO(0), of La(2-x)M(x)M'Cu2Oy (M, M' = Sr, Ca) solid solution was determined by the solution calorimetric method. The enthalpy change of the formation reaction Delta H, of LSSCO, LSCCO and LCCCO from simple oxides, were calculated as a function of x. LSSCO exhibited a remarkable enthalpy change and a dependence of Delta H on x, whereas the enthalpy change and its dependence on x of LSCCO and LCCCO were small. A correlation was found between the heat of reaction -Delta H and the copper valence. These findings were interpreted in terms of the preference of Sr and Ca to the 2a sites. [References: 18]
