Synthesis and Sintering of Nanosize Li2TiO3 Ceramic Breeder Powder prepared by Autocombustion Technique

Abstract

In the present report we prepare nanosize Li2TiO3 breeder powder by auto-combustion technique using cheaper source of Ti (e.g. TiO2) as the precursor material avoiding costly precursor like TiCl4 or Ti-isopropoxide. We find that by controlling the citrate nitrate ratio, the phase formation takes place during the autocombustion stage. The specific surface area of the synthesized powder is 35 m2/g. It has been found that combustion synthesized powder can be sintered at a temperature 1000oC for 2h with a sintered density more than 85%. Density and microstructure of the sintered pellet are compared with sintered sample prepared by solid state route.
