摘要： A mirror is made by applying a coating to a highly reflective surface of a substrate. The coating is prepared from a composition of an alkoxide having the general formula M(OR).sub.n, where M is 0 to 100% titanium, 0 to 25% silicon, 0 to 100% tantalum, or 0 to 15% of a metal ion which forms an alkoxide, R is alkyl from C.sub.1 to C.sub.6 and n is the valence of M, about 1.7 to about 8 moles of water per mole of alkoxide, sufficient alcohol to give a solids content of about 0.5 to about 15%, and a sufficient amount of a suitable acid to prevent cloudiness. The coated substrate is fired at about 200.degree. to about 600.degree. C. to form an oxide coating which is substantially oxygen impervious. Additional layers of the coating may be applied and fired until the oxide coating is about 200 to about 5000A thick, avoiding quarter-wave thicknesses.

摘要： Disclosed is a method of preparing a clear partially hydrolyzed aluminum alkoxide solution by mixing an aluminum alkoxide with about 0.4 to about 1 moles of water per mole of aluminum alkoxide in the presence of sufficient alcohol to give a maximum weight percent of equivalent alumina of 10%. The mixture is then heated until clear, which typically requires a temperature of about 40.degree. to about 60.degree. C. Then sufficient additional water is added to bring the number of moles of water per mole of alkoxide up to at least about 2. The water is added in the presence of sufficient alcohol to give a maximum weight percent of equivalent alumina of about 3%. A polymerized alumina glass can be prepared from the composition by heating it to a temperature of at least 500.degree. C.

摘要： A glass encapsulated semiconductor diode and a method for glass encapsulation of a fusion to form a semiconductor diode is disclosed. The fusion comprises a body of semiconductor material having a PN junction therein and metal electrodes affixed to opposed major surfaces thereof. The fusion is encircled by a ring-shaped glass member with an inner surface of the ring-shaped glass member fused to an edge surface of the body of semiconductor material to form a protective layer overlying the PN junction. The ring-shaped glass member is formed and fused to the edge of the body of semiconductor material by placing the fushion and a prefabricated glass ring, preferably cut from stress relieved glass tubing, encircling the fusion in a furnace. A weight is applied to the upper surface of the prefabricated glass ring. An atmosphere comprising a predetermined mixture of nitrogen and water vapor is established in the fusion furnace and the temperature of the fusion furnace is increased and decreased in accordance with a predetermined program to cause the prefabricated glass ring to soften and fuse to the edge surface of the body of semiconductor material to form a protective layer, comprising the ring-shaped glass member, overlying the PN junction.

摘要： Method for preparing finely divided high purity alumina doped with a small predetermined percentage of magnesia. In the preparation, there is first formed a mixed clear solution of aluminum alkoxide and a small amount of magnesium in the form of alkoxide or water soluble magnesium salt. There is then included with the clear solution a substantial excess of water over that required to completely hydrolyze the alkoxide and there is added thereto a small amount of selected acid which is effective to peptize the resulting slurry. The formed milky slurry is then allowed to become fully peptized to form a clear sol. The clear sol is converted to a finely divided and dried powder either by forming the sol into a gel, which is then dried, and mechanically reduced to a powder status or by spray drying the sol at elevated temperatures which produces the dried powder. Thereafter, the finely divided and dried powder is calcined at a temperature of from about 700.degree. C. to about 900.degree. C., with the crystalline structure of the powder predominately being that of a delta alumina. The preparation of this alumina is very economic and the resulting material is suitable for being isostatically pressed into a tubular form and then sintered to translucent tubular form to a density which closely approaches theoretical.

摘要： Energy-conserving incandescent lamp wherein the envelope has provided on the interior surface thereof a very efficient and economically applied heat mirror which is highly transmissive for visible radiations and highly reflective for infrared radiations, thereby to enhance the conversion of electric energy to visible energy. The heat-mirror coating comprises a two layer Ag/TiO.sub.2 or a three layer TiO.sub.2 /Ag/TiO.sub.2 coating of predetermined thickness. The three layer coating is formed by first applying to the envelope interior surface a thin layer of clear aliphatic alcohol solution having contained therein partially hydrolyzed metallic alkoxide which substantially comprises titanium alkoxide, and which solution contains at most only a limited amount of selected mineral acid. The applied clear solution layer is heat treated to convert same to a thin continuous layer substantially comprising titania. A thin silver layer is applied over the first applied titania coating, preferably by vacuum metallizing, and a second thin layer of solution containing the partially hydrolyzed metallic alkoxide which substantially comprises titanium alkoxide is applied over the silver layer. Thereafter the applied second layer is heat treated to convert same to titania, with the heat treating temperatures and atmospheres controlled so as not to affect the applied silver layer. The two layer coating is applied by omitting the first TiO.sub.2 coating step.
