摘要：
The 10 degrees C isotherm of the H2O-Na2HPO4-(NH4)(2)HPO4 system has been established in the whole concentration range, whereas the 12.1, 11.7 and 5 degrees C isotherms have been established in a limited domain. The measurements have been carried out using the conductimetric method. The polythermal diagram has been drawn between 40 and 5 degrees C and for the domain of high (NH4)(2)HPO4 concentrations. A ternary peritectic transformation has been obtained al 7.1 degrees C.
