Abstract

Some insights into the mechanism of the interference of calcium with the atomization of selenium are evaluated. The mechanisms of stabilization of selenium atomized together with concomitant calcium and by using palladium alone or in combination with mercury and cadmium as chemical modifiers were also considered. The appearance temperature and the activation energy of the atomization of selenium have been evaluated and discussed.
