✦ Synopsis

Isotherms at 0, 10, and 253C of the H 2 O+(NH 4 ) 2 HPO 4 + (NH 4 ) 2 SO 4 ternary system have been established by conductivity measurements in the considered temperature range (0+253C). Tracing the polythermal diagram has allowed to determine the existence domains of the solid phases: (NH 4 ) 2 HPO 4 ' 2H 2 O, (NH 4 ) 2 HPO 4 , and (NH 4 ) 2 SO 4 .
