Nanotubes--Formability; Tantalum compounds--Synthesis;
Tantalum and Sulfur powders were used to form tantalum disulfide and tantalum trisulfide products. Initial reactants were placed in fused quartz ampoules, vacuum-sealed via a torch supplied with hydrogen and natural gases, and then placed in a tube furnace. The tubes were either in single temperature zones in the furnace or straddling two temperature zones, and multiple temperatures were tested in this experiment. The use of iodine as a transporting agent, the furnace temperatures, the positions of the tubes in the furnace, and the stoichiometric amounts of tantalum and sulfur powder used in this experiment were all variables. It was determined by method of x-ray diffraction that higher temperatures result in crystalline tantalum disulfide, while the lower furnace temperatures produce nanostructures, with a mixture of tantalum disulfide and tantalum trisulfide products.
