Evolution of molecular structure during the sol-gel processing of lithium niobate and the development of microstructure in alkoxide-derived thin layers

Lithium niobate powders and thin-layers were prepared by sol-gel processing. Lithium niobium ethoxide and lithium niobium methoxyethoxide bimetallic alkoxides were used for both gel and thin-layer formation. Advantages of sol-gel processing were demonstrated by synthesis of LiNb(OCH$\sb2$CH$\sb3)\sb6$crystals having the proper cation ratio for stoichiometric LiNbO$\sb3$. The alkoxide deposition method also allowed for the formation of layers of uniform quality at 650$\sp\circ$C, thereby, avoiding lithium oxide volatility.
