Coating with Sol-Gel Glasses

The Manufacturing Science & Technology Center conducts process development and scale-up of ceramic and glass materials prepared by the sol-gel process. Sol-gel processing uses solutions prepared at low temperature rather than high temperature powder processing to make materials with controlled properties. A precursor sol-gel solution (sol) is either poured into a mold and allowed to gel or is diluted and applied to a substrate by spinning, dipping, spraying, electrophoresis, inkjet printing or roll coating. Controlled drying of the wet gel results in either a ceramic or glass bulk part or a thin film on a glass, plastic, ceramic or metal substrate.

Sol-gel derived materials have diverse applications in optics, electronics, energy, space, sensors and separation technology.

The department also makes highly porous bulk and thin film aerogels using a sol-gel process. These novel materials have unique properties (>90% porosity, ultra-low density, low thermal conductivity) that lead to applications as acoustic insulation, highly efficient inorganic insulation, low K dielectrics, and as inert porous matrices for sensors or optics.
