Abstract
LiV3O8 ceramic powders have been prepared using a solid state reaction method at different (500°C, 550°C, 600°C and 700°C) temperatures. The X-ray diffraction profiles of these samples show that the ceramic powder sintered at 600°C has a well defined monoclinic structure in a space group of P21/m (11) with lattice parameters, a = 6.68 Å, b = 3.60 Å, c = 12.03 Å and α = γ = 90o and β = 107° and it is found to be in good agreement with the JCPDS Card No. 72–1193. The SEM image of this ceramic powder shows the distribution of grains in cylindrical rods form. Thermal (TG) property of as prepared precursor LiV3O8 chemicals has been investigated. Raman and FTIR spectra of the temperature optimized (600°C) ceramic powder have been carried out. Besides this, its dielectric constant (ϵ′) and tangent loss as a function of frequency (100 Hz–1 MHz) and conductivities (σac and σdc) have also been understood in evaluating its potentialities for different applications.
