Antimony sulfide tetragonal (rectangular) prismatic tubular crystals with d
imenions of 6-10 mm in length, 50-60 mum in width, and 5-15 mum in thicknes
s were successfully synthesized for the first time via a hydrothermal react
ion route from antimony trichloride and sodium thiosulfate in the presence
of ammonium chloride at 198 degreesC.
