摘要:
The present invention relates to a film comprising silicon dioxide as the main component, which contains Zr, etc., and a method for forming it by reactive DC sputtering. It makes it possible to form reflection preventive films, alkali barrier films and various multi-layered films such as multi-layered films for anti-iridescent glass, which contain said film comprising silicon dioxide as the main component, by a physical vapor deposition method without breaking a vacuum.
摘要:
An amorphous oxide film composed essentially of an oxide containing at least one member selected from the group consisting of Zr, Ti, Hf, Sn, Ta and In and at least one member selected from the group consisting of B and Si.
摘要:
A process for producing silica glass fibers comprising:a step of preparing a silica glass fiber spinning solution by adding a polymerization regulator to a silica sol solution obtained by the hydrolysis and condensation of a silicon alkoxide in the presence of an acid catalyst;a step of spinning the spinning solution into gel fibers by extruding the spinning solution from nozzles;a step of applying an oiling agent containing substantially no water or lower alcohol to the gel fibers;a step of forming a fiber cake by winding the oiled gel fibers on a tube or bobbin;a step of aging the gel fibers constituting the fiber cake;a step of sintering the gel fibers unwound from the fiber cake after the aging step, to form silica glass fibers.

A glazing panel carrying a coating stack comprises in sequence at least: a glass substrate a base antireflective layer an infra-red reflecting layer, and a top antireflective layer in which at least one of the antireflective layers comprises at least one mixed nitride layer which is a mixture of Al and at least one additional material X, in which the atomic ratio X/Al is greater than or equal to 0.05 and in which X is one or more of the materials selected from the group comprising the elements of Groups 3a, 4a, 5a, 4b, 5b, 6b, 7b, 8 of the periodic table. The glazing panel is particularly suitable for heat treatment and incorporation in windscreens.
摘要:
A glazing panel carrying a solar control coating stack comprising in sequence at least: a glass substrate base antireflective layer comprising at least one layer comprising a nitride of aluminium an infra-red reflecting layer; and a top antireflective layer. The nitride of aluminium confers, inter alia, good thermal stability on the coating, particularly during heat treatment.
