摘要： Articles of polycrystalline zinc sulfide and zinc selenide achieve substantially improved optical quality by a treatment of heat and isostatic pressure by means of an inert working fluid. The treated specimens are transparent and have substantial transmission in the infrared and visible range of the spectrum. Additional improvement in the transmission characteristics is achieved by wrapping the specimens in a foil of an inert material prior to treatment.

摘要： The method involves prehydrolysing alkoxysilanes and atomizing to droplets which are then cured to hardened beads with no or very low porosity and narrow size distribution by slurrying with aqueous ammonia. The cured beads are mixed with binders and the resulting pastes are compacted to green forms; the greens are sintered to fused silica-like objects at temperatures significantly lower than the melting of silica.

摘要： An image intensifier tube has a faceplate formed of optical material. The outer surface of the faceplate has light receiving and light transmitting surfaces and a layer of a reduced metal oxide material for reducing stray light which is transmitted into the faceplate and reflected off of internal surfaces thereof. The layer has a blackened appearance and is formed by reducing the metal oxide of the faceplate material with hydrogen at a predetermined pressure and temperature to cause the blackening to reach a depth sufficient to reduce transmission of stray light therethrough.

摘要： This invention is directed to the preparation of glass articles exhibiting a relatively broad band of high contrast polarizing properties in the infrared region of the radiation spectrum from glasses containing silver halide particles selected from the group consisting of AgCl, AgBr, and AgI. The inventive method comprises the following five general steps:(a) melting a batch for a glass containing silver and at least one halide selected from the group consisting of chloride, bromide, and iodide;(b) cooling and shaping said melt into a glass article of a desired configuration;(c) subjecting said glass article to a temperature at least above the strain point, but not in excess of 75.degree. C. above the softening point of the glass, for a sufficient length of time to cause the generation of silver halide particles therein selected from the group consisting of AgCl, AgBr, and AgI, said particles ranging in size between about 200-5000 .ANG.;(d) elongating said glass article under stress at a temperature above the annealing point, but below that where said glass exhibits a viscosity of about 10.sup.8 poises, such that said silver halide particles are elongated to an aspect ratio of at least 5:1 and aligned in the direction of the stress; and, thereafter,(e) exposing said elongated glass article to a reducing environment at a pressure greater than atmospheric pressure and at a temperature above about 250.degree. C., but no higher than about 25.degree. C. above the annealing point of the glass, for a period of time sufficient to develop a reducing surface layer on said glass article having a thickness of at least 10 microns wherein at least a portion of said elongated silver halide particles are reduced to elemental silver particles having aspect ratios greater than 2:1 which are deposited in and/or upon said elongated particles.

摘要： This invention is directed to a method for heat treating a sheet of a potentially photochromic glass to cause the growth of silver halide crystals therein which impart photochromic properties thereto, wherein the heat treated sheet will be essentially free from thermal deformation and surface defects, and the photochromic properties exhibited therein will be essentially uniform across the area of the sheet. The method involves first placing a sheet of potentially photochromic glass on top of a sheet of carrier glass that exhibits a softening point at least 50.degree. C. higher than the temperature at which the potentially photochromic glass will be heat treated, and thereafter subjecting the stacked sheets to the heat treatment temperature desired for growing silver halide crystals in the glass.

摘要： An improved quality vitreous silica boby and/or improved quality product made at high temperature in a vitreous silica vessel is/are obtained by applying a polarizing potential across the boundary surfaces of the vitreous silica body or vessel to cause migration of impurity ions away from one of the boundary surfaces thereof. Single crystal silicon (10) of reduced alkali content is drawn from melt (12) in a vitreous silica crucible (14) with a polarizing voltage applied across the wall of the crucible.
