Box 5800, Albuquerque, New Mexico 87185 mdnyman@ sandia.gov Lithium niobates and tantalates have a number of characteristics exploitable for optical and electrical devices that include ion conductivity, self-activating or dopant luminescence, piezoelectricity, pyroelectricity and ferroelectricity. To form these materials as nanometric powders or thin-film coatings, soft-chemical processing is required, and a limited number of procedures have been reported. We have explored two soft-chemical routes to lithium niobate and lithium tantalate materials: a non-aqueous procedure and an aqueous procedure. The non-aqueous procedure, which utilizes 1,4-butanediol and simple chemical precursors produces pure phase rhombohedral LiTaO3 and LiNbO3. For aqueous synthesis, we utilize the

The products are characterized by powder X-ray diffraction, scanning electron microscopy, transmission electron microscopy, compositional analysis, and thermogravimetry, and the two soft-chemical processes are compared. © 2009 American Chemical Society.
