Fabrication of Lithium Silicate Doped with Lithium Titanate by Solid-state Reaction and Its XRD Study
Fabrication of lithium silicate powder doped with lithium titanate by solid-state reaction.Take lithium carbonate,silicon dioxide and titania as raw materials and then these powders were mixed according to the different ratios and grinded in an agate mortar for 15 min.And then the mixture were dried at 80℃.Finally,the samples were sintered in vacuum tube furnace at 750,800,850 and 900℃ for 2h.Thermogravimetric analysis,differential scanning calorimetry and XRD analysis were carried out systematically in this paper.The reaction process and mechanism at different temperatures and the effect of the different ratios and sintering temperature were discussed.Experimental results showed that lithium titanate component increased with increasing amount of titanium dioxide.While the mixture were sintered at 900℃ for 2h,there would have lithium silicate and lithium titanate phase.
