Preparation of LiTaO₃, LiNbO₃, and NaNbO₃from Peroxide Solutions

Vibrational Spectra of Eight‐Coordinate Niobium and Tantalum Complexes with Peroxo Ligands: A Theoretical Simulation

“…[6,7] Finally, because such peroxotype coordination compounds are most of the time soluble in water, they are also of great interest as precursors for the preparation of oxide materials and, more particularly, multimetallic oxides involving highly polarizing d 0 transition metals like Ti , for which the availability of water-soluble compounds is very limited. [8][9][10][11][12][13] "peroxo way" has recently been shown to be a valuable approach for the synthesis of mixed oxides containing niobium and/or tantalum from well-defined and pre-isolated complexes. [14,15] The peroxo compounds of transition metals correspond either to homoleptic complexes or to heteroleptic ones.…”

Solution‐Phase Synthesis of Crystalline Lithium Niobate Nanostructures

“…[6, 10,11] A variety of other soft-chemical routes exist for the synthesis of metal oxides. In fact, a number of these approaches have already been pursued for the synthesis of LiNbO 3 .…”

“…In fact, a number of these approaches have already been pursued for the synthesis of LiNbO 3 . These syntheses include the thermal degradation of water soluble peroxides, [10] malic acid [9] and oxalic acid-based powders, [6a] as well as the hydrothermal [2] and sol-gel treatment of alkoxides.…”

Preparation of nanocrystalline lithium niobate powders at low temperature

“…Evaporation of volatile components during long-term, high-temperature solid-state synthesis may lead to uncontrolled changes in the Li:Nb ratio in the reaction product, which may yield not only LiNbO 3 but also Li 3 NbO 4 and LiNb 3 O 8 components in the whole system [21]. Xue et al [22,23] have reported the preparation of high-quality LiNbO 3 powders with urea as fuel at 550-600 °C.…”
