Abstract Bulk amorphous sulfur (a-S) with 1 mol% of phosphorus, selenium and iodine additives and bulk amorphous pure sulfur samples were prepared by rapidly compressing the melts to 2 GPa within 20 ms. The results of x-ray diffraction, differential scanning calorimetry and in situ wide angle x-ray scattering of the recovered samples are presented and discussed. In the iodine doping case, obvious inhibiting effects on the crystallization and the melting process under high temperatures occurred, as well as on the structure relaxation of a-S at room temperature, suggesting that the thermal stability of amorphous sulfur is remarkably improved by the introduction of iodine additives.
