Abstract

A preparative technique based on the gelation of a microemulsion has provided a means of homogeneously dispersing high concentrations of metal oxide precursor salts through silica gel. The microstructures and compositions of gels containing combinations of lithium and manganese nitrate, and of the multiphase materials obtained by firing to a range of temperatures up to 1000°C, have been established. Formation of the mixed metal oxide spinel phase LiMn2O4 within a silica support has been obtained for systems comprising from 10 to 30 wt% metal nitrate by heating to temperatures between 500 and 700°C.
