Superconducting oxides in the A, B, Cu oxide ternary system, where A is yttrium or a rare earth and B is an alkaline earth, are formed as thin films on a substrate by a sol-gel technique.

Method for fabricating superconductors by sol-gel process

Luminescent thin films are produced by a sol-gel process in which a gellable liquid is applied to a substrate to form a thin film, gelled and heated to remove volatile constituents and form a polycrystalline luminescent material.

Sol-gel process for producing liminescent thin film, and film so

A thin film capacitor is formed of a thin crystalline electrically insulative or semiconductive substrate. With the insulative substrate a thin conductive metal layer is deposited on the substrate and a thin film of a crystalline strontium barium niobate deposited on the thin conductive metal layer so that its 2.77.ANG. spaced atomic planes are oriented in a non-perpendicular manner to the substrate and an additional thin conductive layer is deposited on the surface of the strontium barium niobate film. When a semiconductive substrate is employed the strontium barium niobate film is deposited directly on the substrate. These capacitors exhibit a low temperature coefficient of capacitance and a high capacitance density.

A reliable garnet to metal hermetic seal is obtained by metallizing the garnet with successive sputtered layers of tantalum or titanium, molybdenum or tungsten and nickel, followed by soldering or brazing the metallized garnet to a metal member.
