INVESTIGATIONS ON SOME PURE AND DOPED (Na2-XLiXTi3O7)

In assessing the possibilities of high ionic conduction needed for battery application various Li containing materials particularly those with structural arrangements containing tunnels or diffusion paths have been examined. Alkali titanates with unique layered and tunnel crystal structure have very good physico-chemical properties, such as optical properties, ionic and electronic conductivities, have been investigated on account of their application in the industries as ion exchangers, electrode for secondary batteries, filters, reinforcements, heat insulators and catalysts.Due to cation exchange property, some of alkali titanates are under consideration to protect environment from the lethal radiation of highly radioactive wastes. A sodium titanate material, mono-sodium titanate serves as the base line material at the Savannah River site USA for strontium and actinide separations from HLW-solutions. In Oak Ridge National Laboratory sodium titanate is used as sorbent material to decontaminate ground water from Sr90 and Cs137. Infrared sensors, which are used in night vision device, may be designed using information from pyro electric investigations of these ceramic materials.
