摘要

Research has been carried out on two families of solids. The 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, liquid and solid state NMR. A new theory was developed on gel transformations. A number of new composites made by the sol-gel route were examined, including the use of silicon carbide and diamond powder as fillers and some triphasic solids. Many ferroelectric thin films were prepared and their properties measured. An inorganic-organic gel material named ORMOSIL was developed which developed which exhibited rubbery elasticity. 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 spectroscopy. The interaction of ultraviolet radiation on chalcogenide fibers was investigated.
