摘要： A liquid polymer is formed in a low temperature polymerization reaction involving organo-metallic sodium and aluminum compounds, at least one of which is partially hydrolyzed. The polymer is hydrolyzed, dried to form an amorphous sodium Beta-alumina precursor, and then heated, at between 1,200.degree. C. and about 1,550.degree. C., to form a ceramic, comprising ion-conductive sodium Beta-alumina which is useful as a solid electrolyte.

摘要： Liquid comprising from 93 to 100 percent by weight alcohol is removed from silica alcogel at subcritical temperature to produce silica aerogel. The silica aerogel produced by the method of the present invention not only has high porosity, but in most instances it also has a narrow distribution of small pore sizes. The silica aerogel is preferably reduced in size so as to form particulate silica aerogel.

摘要： A composite material having a fiber system embedded in a host matrix material. The fiber system has a protective reaction barrier around the embedded fibers to prevent deleterious chemical or mechanical reaction between the fiber and matrix. The fiber coating is applied by immersion of the fiber system into an alkoxide solution of the desired oxide precursor with controlled immersion and withdrawal rates with subsequent drying, heating to convert to a pure oxide state, and where required, post processing, to convert the oxide coating to a carbide or nitride, for example.

摘要： The absorption of neutrons of a nuclear reactor without producing fissions is reduced by providing selected isotopes of zirconium for fabrication of parts such as cladding, thimble tubes and grids. Specifically, the zirconium is enriched in .sup.90 Zr or is depleted in .sup.91 Zr. The selected isotopes are produced by irradiating Zr(OC.sub.4 H.sub.9).sub.4.sup.t, Zr(OC.sub.5 H.sub.11).sub.4.sup.t and/or Zr(OC.sub.3 H.sub.7).sub.4.sup.t, with radiation from a CO.sub.2 laser tuned to the vibrations of the CO(.sup.90 Zr) bond or the O(.sup.91 Zr) bond.

摘要： Antireflective silica coating for vitreous material is substantially non-reflecting over a wide band of radiations. This is achieved by providing the coating with a graded degree of porosity which grades the index of refraction between that of air and the vitreous material of the substrate. To prepare the coating, there is first prepared a silicon-alkoxide-based coating solution of particular polymer structure produced by a controlled proportion of water to alkoxide and a controlled concentration of alkoxide to solution, along with a small amount of catalyst. The primary solvent is alcohol and the solution is polymerized and hydrolized under controlled conditions prior to use. The prepared solution is applied as a film to the vitreous substrate and rapidly dried. It is thereafter heated under controlled conditions to volatilize the hydroxyl radicals and organics therefrom and then to produce a suitable pore morphology in the residual porous silica layer. The silica layer is then etched in order to enlarge the pores in a graded fashion, with the largest of the pores remaining being sufficiently small that radiations to be passed through the substrate are not significantly scattered. For use with quartz substrates, extremely durable coatings which display only 0.1% reflectivity have been prepared.

摘要： A clear solution is prepared by reacting metal alkoxide with a mixture of critical amounts of water and/or acid in an alcohol diluted medium. Alkoxides may be Ti(OR).sub.4 or Ta(OR).sub.5, or another metal alkoxide such as Si(OR).sub.4 in admixture with these alkoxides. Acids may be HCl or HNO.sub.3. Quarter wave inorganic optical coatings are deposited by applying the alkoxide solution to a substrate then heating the coating at over 350.degree. C. The coatings reduce reflectivity on silicon solar cells. The index of refraction of the coating can be varied by several techniques, including altering the proportion of titanium and silicon in the coating firing temperature, firing atmosphere. Thicknesses of the coating can be controlled by varying the rpm in spin application, withdrawal rate in dipping application, by concentration of the solution, by the type of solvent or the degree of polymerization of the titanium complexes.

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.
