Abstract

Nanocrystalline CuAlS2 chalcopyrite has been mechanosynthesized at room temperature for the first time by ball milling the stoichiometric mixture of elemental of Cu, Al, and S powders under argon atmosphere. Initially, the CuAlS2 phase is formed by solid state reaction of elemental powders within 15 min of milling and in the course of milling crystallite size decreases slowly to ~5 nm within 10 h of milling. Microstructure characterization and phase transformation kinetics of the elemental powders toward the chalcopyrite phase formation has been made by employing the Rietveld analysis using X-ray diffraction data of unmilled and ball-milled samples.
