Sol-gel processing of electrical and magnetic ceramics

Preparation and Characterization of Ultrafine Rare Earth Molybdenum Complex Oxide Particles

“…In the present study, ultrafine La-Mo and Ce-Mo complex oxide particle catalysts were prepared by a modified sol-gel method, as reported in the literature (13,20,26), in which citric acid was used as a complexing polyfunctional hydroxy acid. With a citrate (M(OOCR) L ) as a precursor, sol-gel chemistry can be described in terms of two classes of reactions:…”

Preparation and Characterization of VO2 Nanopowders

“…This phase transition is associated with abrupt changes in optical and electrical properties; therefore, VO has potential applications, for example, in preparing thermal and optical switches (2,3). Although various technologies have been developed for producing VO "lms (4,5), few convenient ones have been found for making VO powders. The typical method of preparing VO powders is to heat a mixture of V O (or V) and V O corresponding to VO composition in an evacuated silica tube at 7003C for 2 days (6), or to reduce V O powder in a platinum crucible under an inert atmosphere at 1200}13503C for 3 days (7,8).…”

Chemical Solution Deposition—Basic Principles

“…Some key investigations in this area are summarized in Refs. [5][6][7][8][9][10][11][12]and Refs. 112 and 113 also contain detailed information on the analysis of structural evolution processes.…”
