- The pressure-temperature structural phase diagram of NaBH4 has been mapped by thermal conductivitymeasurements below room temperature and up to 2 GPa. The critical transition temperature for the transformationfrom the low-temperature tetragonal structure to the room temperature cubic one increases from near190 K at zero pressure to about 235 K at 2 GPa. The thermal conductivity data are consistent with theorder-disorder character of the transition.
