262	Glaze polishing polycrystalline alumina material	US895965	1986-08-12	US4690727A	1987-09-01	Curtis E. Scott; Charles I. McVey
Increased optical transmission is provided for a body of optically transparent polycrystalline alumina by coating at least one major surface of said alumina body with a solid glaze coating and subsequently melting said coating at elevated temperatures to dissolve the surface alumina grains in physical content therewith to provide a smoother surface when the coating residue has been removed. More particularly, a solid glaze coating is first deposited on said major surface of the alumina body and the coated alumina body thereafter heated to sufficiently elevated temperatures for the glaze liquification whereupon surface alumina grains in physical contact therewith are dissolved in a manner which reduces the high spots on the individual surface alumina grains without materially introducing low spots at the grain boundaries and wherein the individual alumina surface grains have been preferentially etched in certain of the crystalline axis directions. The present glaze material comprises an alkali metal borate other than lithium borate having an alkali metal oxide to boron oxide weight ratio in the range from about 1:2 up to 1:4 and which is deposited on the major surface of said alumina body as a liquid suspension.

264	Surface preparation of ceramic substrates for metallization	US679220	1984-12-07	US4647477A	1987-03-03	Michael A. DeLuca
A process for preparing a ceramic substrate for metallization wherein a surface of the ceramic substrate is contacted with an admixture comprised of an inert solid material and a composition containing one or more alkali metal compounds. The admixture and the substrate are heated at least to a temperature at which the alkali metal composition becomes molten. The molten alkali metal composition is kept in contact with the ceramic surface for a time period sufficient to etch the surface and thus prepare it for adherent deposition of metal. The presence of the inert solid material in the admixture prevents coalescence of the alkali metal composition on the ceramic surface. Uniform surface coverage with catalyst and metal and an adherent bond of metal to the ceramic surface are ensured by treatment with the admixture. Furthermore, an article comprised of metal directly and adherently bonded onto a ceramic substrate is provided.

266	Process for the removal of impurities from optical component materials	US640724	1984-08-14	US4600442A	1986-07-15	Ricardo C. Pastor; Luisa E. Gorre
A process is disclosed for the removal of water and water derived impurities, e.g. OH.sup.-, substitutionally or interstitially incorporated in the structure of crystalline and amorphous materials, more specifically, in metal oxides, e.g. fused silica or aluminum oxide, wherein the material is exposed in powdered form to a gaseous mixture of halogen and carbon monoxide at a predetermined elevated temperature. The mixture of halogen and carbon monoxide reacts to cause the water and OH.sup.- ion concentration in the processed material to be reduced to an extremely low level. Materials purified by the process can be used to produce optical fibers and laser windows of excellent mechanical, thermal and optical properties.

268	Electrolysis treatment for drawing ions out of a ceramic	US514718	1983-07-18	US4466820A	1984-08-21	David R. Clarke
A method is provided for drawing ions out of the glassy phase of a ceramic in order to improve its high temperature strength and to reduce its dielectric loss. The ceramic is heated to a high temperature to increase the mobility of the ions within the glassy phase. An electric field is then applied across the ceramic to draw the ions to the surfaces of the ceramic where they can be removed by grinding.
269	Repair of reinforced concrete structures by mineral accretion	US234321	1981-02-13	US4440605A	1984-04-03	Wolf H. Hilbertz
By establishing a direct electrical current between electrodes in an electrolyte, such as seawater or fresh water containing minerals in solution, calcium carbonates, magnesium hydroxides, and hydrogen are precipitated at the cathode, while at the anode, oxygen and chlorine are produced. The electrochemical precipitation of minerals at and in the vicinity of metal reinforcement in a reinforced concrete structure is utilized to repair damaged portions thereof, for example, fractures, cracks, fissures, and voids.To repair reinforced concrete structures, the structure is disposed in a volume of electrolyte. The metal reinforcement is made a cathode by connection to the negative terminal of a suitable DC power supply. One or more anodes are disposed in proximity to the structure, and a direct electrical current is established between the electrodes for a period of time sufficient to fill by accretion cracks, fissures or voids in the concrete body of the structure.

A process for the manufacture of a rigid foam out of a slurry containing an alkali silicate, or foaming agent, a substance which produces a gradual reaction with the alkali silicate, and other additives. It is essential that dinitrosopentamethylenetetramine be included in the slurried mixture. Such an undesired decomposition residuum as formaldehyde that may be produced by this compound is removable either by the combined use of a ureal substance or by an additional heat treatment of the slurry.

The concentration of silicate in solution is limited to avoid frosting and discoloration when subjected to heat. The clear solution includes clay and a binder for mar resistance and adhesion. The opaque solution includes a pigment and a binder.
276	Dual-etched refractory metallizing	US3661635D	1970-02-20	US3661635A	1972-05-09	HARRISON HENRY F
A process for metallizing on ceramic substrates with fine detail patterns of refractory metal which includes a prefiring to effect oxidation of a portion of the metallizing coating, application of a photopolymerizable coating thereover followed by exposure in pattern form using a mask, removal of unpolymerized coating by conventional means, acid etching to remove the oxides formed during pre-firing in exposed portions of the metallizing coating and mechanical removal of unoxidized and unsintered metal remaining in etched portions. This is followed by a final firing which destroys the photoresist and sinters the metal remaining on the substrate.
