Electroconductive silver composition

A mixture of carboxylate and diketonate coating reactants is disclosed to form a metal oxide film with essentially the same reflectance and transmittance properties as a metal oxide film formed from diketonate coating reactants alone, while providing improvement in the control of defects in the film.

Pyrolytic coating reactant for defect and durability control

An electroconductive film comprising the oxides of cobalt and nickel in a spinel structure having the formula NiCo.sub.2 O.sub.4 and having high absorption in the luminous and infrared portions of the solar energy spectrum is disclosed.

Conductive metal oxide film for solar energy control

A glass substrate is modified by enriching a surface portion of the substrate with a metal such that the refractive index of the surface portion is different from that of the unmodified glass matrix. The modified surface is then coated with a metal oxide film to produce durable articles in a variety of interference-type colors suitable for architectural use to control incident solar energy.

Method of making colored glass articles

A composition suitable for producing a metal oxide coating on the surface of a heated refractory substrate is disclosed. The composition comprises a metal beta diketonate dissolved in a nonflammable, high-boiling, halocarbon-containing solvent mixture. The solvent mixture has surprisingly high solubility for transition metal beta diketonates. Because of the nonflammability and high-boiling characteristics of the solvent mixture, the composition is particularly useful for coating freshly formed float glass.

Nonflammable beta diketonate composition

A coating apparatus employing a continuous traveling chain to move coating composition dispensers across a conveyer for coating glass traveling on the conveyer is provided with at least two sets of coating dispensers, all positioned for dispensing coating composition generally normal to a plane in which the chain travels, with the sets of coating dispensers actuated during separate portions of their travel along the path of the traveling chain in order to continuously produce multiple film coatings as the dispensers remain oriented throughout their travel in facing relation to the conveyer.

Apparatus for coating an advancing substrate

Glass is heated to a temperature of at least about 400.degree. C. and contacted sequentially with a silane-containing gas and an organometallic composition which thermally decompose to form, respectively, a coating layer of silicon and a coating layer of metal oxide on the glass surface. The resultant coated glass article is more durable than a silicon coated glass article and has better solar energy control properties than a metal oxide coated glass article.

Method for coating glass with silicon and a metal oxide and resulting

Multiple layer films of silver-silver oxide and metal oxide are produced on transparent substrates for purposes of solar energy control and production of architectural colors. Solar control properties and the transmitted and reflected colors of the article can be altered by varying the thicknesses of the films and/or the selection of metal oxide overcoat. The article produced can be used in a viewing closure and as a component in a solar energy collection system.
