Abstract : Research has been carried out on two families of solids. This first one involves solids made by the sol gel process and includes composites. The second one involves non-oxide glasses based on fluorides, chalcogenides and chalcohalides. The structures of oxide gels were studied by X ray photoelectron spectroscopy, and the gelation of gels investigated as a function of temperature and catalyst. A new theory was developed on gel transformations. A number of new composites made by the sol gel route were examined included the using of SiC and diamond powder as fillers and some triphasic solids. The viscosity and viscoelasticity of fluorozirconate glasses and glass fibers have been studied. New chalcohalide glasses were prepared and their optical properties evaluated. Structural information was derived from Raman spectra. Keywords: Halide glasses, Porous glass-polymer composites, Fluorozirconate glasses, Porous glass ferroelectric composites.
