Thermal crystallization behavior of ${\mathrm{As}}_{\mathit{x}}$${\mathrm{Te}}_{100\mathrm{\ensuremath{-}}\mathit{x}}$ (25\ensuremath{\le}x\ensuremath{\le}60) glasses is studied by differential scanning calorimetry. ${\mathrm{As}}_{\mathit{x}}$${\mathrm{Te}}_{100\mathrm{\ensuremath{-}}\mathit{x}}$ glasses with x40 are found to exhibit one glass transition and one crystallization reaction, during heating. On the other hand, glasses with 40\ensuremath{\le}x\ensuremath{\le}50 show one glass transition and two crystallization reactions. Unlike other binary telluride glasses, the first crystallization reaction in ${\mathrm{As}}_{\mathit{x}}$${\mathrm{Te}}_{100\mathrm{\ensuremath{-}}\mathit{x}}$ glasses does not correspond to the precipitation of hexagonal Te. It corresponds to the formation of a metastable intermediate crystalline phase, which transforms into the equilibrium ${\mathrm{As}}_{2}$${\mathrm{Te}}_{3}$ phase at the second crystallization reaction. As a consequence of this difference in the crystallization behavior, ${\mathrm{As}}_{\mathit{x}}$${\mathrm{Te}}_{100\mathrm{\ensuremath{-}}\mathit{x}}$ glasses with 40\ensuremath{\le}x\ensuremath{\le}50 do not show the phenomenon of double glass transition. Further, the two crystallization reactions of these glasses are found to merge progressively, with the increase in arsenic content. As a result, ${\mathrm{As}}_{\mathit{x}}$${\mathrm{Te}}_{100\mathrm{\ensuremath{-}}\mathit{x}}$ glasses with 50x\ensuremath{\le}60 show only one crystallization reaction. An explanation for this interesting crystallization behavior of ${\mathrm{As}}_{\mathit{x}}$${\mathrm{Te}}_{100\mathrm{\ensuremath{-}}\mathit{x}}$ glasses is provided with the help of x-ray diffraction, electron microscopy, and thermogravimetry studies.
