Single step synthesis of Li2TiO3 powder

A novel process method based on solid liquid combustion synthesis has been developed to produce high purity monoclinic Li2TiO3 directly after combustion. The process does not call for any additional heat treatment for phase formation. The lattice parameters of Li2TiO3 were determined through Rietveld refinement of XRD pattern. Systematic studies were carried out to optimize the sintering temperature to obtain the desired microstructure and density in the sintered specimens. The morphology of Li2TiO3 powder and microstructures of sintered specimens were studied by scanning electron microscopy. The powder produced through this route could be sintered to 90% of theoretical density at relatively low temperatures (<1150 degrees C). The process developed in the present investigation is simple and convenient for mass production. (C) 2010 Elsevier B.V. All rights reserved.
