An [[activation energy|energy barrier]] was found for the nonstoichiometric vaporization of arsenic due to the irregularity of the partial pressures with temperature. The range of the energy gap is from 0.5 to 0.6 eV. Cd<sub>3</sub>As<sub>2</sub> melts at 716&nbsp;°C and changes phase at 615&nbsp;°C/<ref name=doi1073>{{Cite journal | doi = 10.1007/BF00551073| title = On the preparation, growth and properties of Cd<sub>3</sub>As<sub>2</sub>| journal = Journal of Materials Science| volume = 4| issue = 9| pages = 784–788| year = 1969| last1 = Hiscocks | first1 = S.
