Metal alkoxides are widely used for the production of ceramic oxide materials.  As an alternative set of precursors, metal siloxide for production of ceramic siloxide materials are less explored.  Therefore, a study focused on the synthesis, characterization, and nanomaterials of a family of silanol modified metal alkoxides was undertaken.  The silanols investigated were generated from commercially available (triphenyl silanol, dimethyl, butyl silanol, tris-tributoxy silanol, etc) and in-house synthesized (tirmethylsilyl silanol or H-SST) modifiers.  The products were identified by a variety of analytical methods.  Once isolated, attempts to generate metal siloxides were undertaken.  While most derivatives led to the ceramic oxide, the SST derivatives generate a core@shell geometry as identified by TEM analysis.  Full details of the preparation of the precursors and the subsequent materials will be presented.<br/> <br/>--------------------<br/>Sandia National Laboratories is a multi-program laboratory managed and operated by Sandia Corporation, a wholly owned subsidiary of Lockheed Martin Corporation, for the U.S. Department of Energy’s National Nuclear Security Administration under contract DE-AC04-94AL85000.<br/>
