Structural characterization of LiCrxMn2−xO4 via a simple reflux technique

Abstract

Abstract. LiCr x Mn 2-x O 4 (x=0; 0.02; 0.04; 0.06; 0.08, 0.10) have been successfully synthesized via a facile and simple reflux technique. The SEM-EDS data confirm the presence of Cr, Mn and O elements in the products, while the XRD pattern suggests that the materials have well-developed cubic crystals. Direct method was applied to extract structural parameters of LiCr x Mn 2-x O 4 using the Fullprof and Oscail software in WinPlotr package program. Materials were refined in the crystal system, and space group of structures Fd3m phase were then identified. The lattice parameters decrease with the decrease in Cr content. The highest Li-O bond length was found for LiCr 0.10 Mn 1.90 O 4 . It was observed that there is no significant change in particle size as Cr content increased.
