Abstract
A 100-nm CuFeS2 ultrafine powder was prepared through a solvothermal reacti on at 200-250 degrees C. X-ray powder diffraction and transmission electron microscopy results revealed that chalcopyrite-phase CuFeS2 was crystallize d with single-crystalline nature and preferential orientation growth. Mossb auer spectrum exhibited a six-peak hyperfine magnetic spectrum and a single nonmagnetic peak. Elemental analysis gave the atomic ratio of Cu:Fe:S of 1 :1.02.2.10. The influence factors on the formation of CuFeS2 ultrafine powd er are discussed.
