Abstrakt: A trial was performed to study the thermal decomposition of sodium hydride with DTA within the temperature range of 500 to 800 K. The best description of this process is provided by the Avrami equation $$\alpha = 1 - e^{ - kt^3 } $$ . The activation energy of this processEa=115 kJ/mole and the frequency factorZ=2·107 sec−1 were determined.
