Lithium niobate hollow spheres and octahedra with rough surfaces have been successfully fabricated from a novel H2(H2O)Nb2O6 precursor by in situ combustion treatment. X-ray diffraction and scanning electronic microscopy were used to study the phase composition and microstructure of the obtained lithium niobate. Experimental results demonstrated that H2(H2O)Nb2O6 hollow spheres and octahedra can be facilely transformed into their corresponding hexagonal phase LiNbO3 crystallites without destroying the microstructures, even though through an intense combustion treatment. These hollow and rough octahedral structures may open up large perspectives for LiNbO3. The present in situ conversion strategy by coating flexible H2(H2O)Nb2O6 precursors to form microscopic reactors could also be extended to other niobates with various structures.
