Abstract

The selenogallates CsGaSe3 and Cs2Ga2Se5 release gaseous selenium upon heating. An in situ high-temperature X-ray powder diffraction analysis revealed a two-step degradation process from CsGaSe3 to Cs2Ga2Se5 and finally to CsGaSe2. During each step, one Se22– unit of the anionic chains in Cs2[Ga2(Se2)2–xSe2+x] (x = 0, 1, 2) decomposes, and one equivalent of selenium is released. This thermal ...
