Abstract

The heat capacity of α-beryllium nitride. Be₃N₂, was determined from 20 to 315 K and the thermodynamic properties calculated from 0 to 315 K. The entropy at 298.15 K was found to be 34.4 ±0.3 J/K· mol (8.23 ±0.08 cal/K· mol). The precision using a calorimeter of a new design is shown to be ± 0.01 percent over most of the temperature range of the measurements.
