Abstract

DTA and DTP (differential thermal pyrosynthesis) procedures have been used to study the formation kinetics of synthetic Sb (sub 2) AsS (sub 2) . A new redefined XRD pattern is given, with 2.878(100), 1.752(78), 2.683(77), 2.277(75), 1.977(68) Aa, a 10.75, b 3.959, c 12.49 Aa, beta 115.25 degrees ; all other optical and chemical properties exactly match those of natural Sb (sub 2) AsS (sub 2) . The Sb (sub 2) AsS (sub 2) compound, which melts incongruently at 530 degrees C to give stibarsen and a stibnite-like melt, may be synthesized easily either through a controlled solid-state reaction or through a combination of solid-state and solid-melt reactions (as a function of the scan rate of the DTP experiments). The similarity of the Sb (sub 2) AsS (sub 2) structure with that of stibnite explains the small amount of energy required for its formation.
