摘要： The instant invention is directed to the production of highly polarizing glasses, i.e., the glasses exhibit dichroic ratios up to 40 and higher, from silver-containing glasses that are characterized as being phase separable or, more preferably, as being photochromic because of the presence of silver halide particles therein, i.e., particles selected from the group of AgCl, AgBr, and AgI. The inventive method contemplates two general steps:(a) the glasses are elongated under stress such that the glass phases and/or silver halide particles are elongated and aligned in the direction of the stress; and(b) the elongated glasses are heat treated in a reducing environment at temperatures below the annealing point of the glass but above about 300.degree. C. to reduce a portion of the silver ions in the glass to metallic silver which is deposited in at least one of the glass phases and/or along the phase boundaries of the glass phases and/or deposited upon the silver halide particles.

摘要： The present invention relates to the preparation of polarizing glasses from silver-containing glasses characterized by the presence of metallic silver particles therein and/or by being photochromic through the inclusion of silver halide particles therein selected from the group of AgCl, AgBr, and AgI. The method contemplates extruding the glass at a temperature between the annealing and softening points of the glass at a sufficiently high applied pressure to elongate the metallic silver and/or silver halide particles to an aspect ratio of at least 2:1 and up to 30:1 and greater. The extrudate is cooled in a manner to prevent the elongated particles from resuming their original shape. Dichroic ratios of up to 5.0 are achievable where the elongated particles exhibit an oblate configuration.
摘要翻译：本发明涉及由含银玻璃制备偏光玻璃，其特征在于其中存在金属银颗粒和/或通过在其中选择AgCl，AgBr和AgI中包含其中的卤化银颗粒进行光致变色。该方法考虑在足够高的施加压力下在玻璃的退火和软化点之间的温度下挤出玻璃以将金属银和/或卤化银颗粒细长至至少2:1至高达30:1的纵横比。 1及以上。挤出物被冷却以防止细长颗粒恢复其原始形状。可以实现高达5.0的二向色比，其中细长颗粒呈现扁圆形结构。

摘要： There is disclosed a composite body that is electrically insulating, and that is composed of metal particles dispersed in a continuous glassy matrix as a second phase. The metal particles are directionally anisotropic generally paralleling a predetermined plane through the body. This permits good thermal conductivity, while retaining the electrical insulating character of the glass, thus providing improved packaging for electronic components. A method of forming the composite body is also disclosed, as are methods of creating improved electronic packaging utilizing the composite material body.
