The UC-UN solid solution, UC<SUB>1-x</SUB>N<SUB>x</SUB>, exists stably in monophase within a certain range of nitro-gen pressure at constant temperature. At the upper limit of this range, UC<SUB>1-x</SUB>N<SUB>x</SUB> coexists with UC<SUB>2</SUB> or with carbon, and it precipitates metallic uranium at the lower limit which corresponds to the de-composition pressure of UC<SUB>1-x</SUB>N<SUB>x</SUB>.<BR>In order to measure the decomposition temperature of UC<SUB>1-x</SUB>N<SUB>x</SUB> with given x under constant nitrogen pressure, it is necessary to heat UC<SUB>1-x</SUB>N<SUB>x</SUB> without changing its composition, at a constant pressure.<BR>In the present work, preliminary considerations have been given to change in composition. Ex-periments were also performed in which the solid solution was heated at a rate of 200°C/min under different nitrogen pressures.<BR>From the results, it is concluded that there exists a temperature range within which the value of x in UC<SUB>1-x</SUB>N<SUB>x</SUB> is maintained constant when the nitrogen pressure is fixed.
