    摘要： METHOD OF FORMING A LIGHTWEIGHT OPTICAL STRUCTURE SUCH AS A MIRROR OR WINDOW MADE UP OF AN OPTICAL PLATE OF QUARTZ FUSED TO A PERFORATED SUPPORT PLATE OR QUARTZ OR FUSED SILICA BY PLACING THE OPTICAL PLATE ON THE PERFORATED SUPPORT PLATE IN SUCH POSITION THAT THE REAR SURFACE OF THE OPTICAL PLATE COVERS THE PERFORATION OPENING, AND DIRECTING A HIGH INTENSITY, HIGH TEMPRATURE SOURCE OF RADIANT HEAT ONTO THE OPTICAL SURFACE OF THE OPTICAL PLATE WHEREBY TO PREFERENTIALLY HEAT THE AREAS OF CONTACT BETWEEN THE OPTICAL PLATE AND THE WALLS OF THE PERFORATED SUPPORT TO SELECTIVELY FUSE SUCH AREAS AND TO CAUSE A PORTION OF THE REAR FACE OFTHE OPTICAL PLATE TO DEFORM AND CONVEXEDLY DEPEND INTO THE PERFORATIONS OF THE SUPPORT PLATE. THE RESULTING OPTICAL STRUCTURE IS ALSO DESCRIBED.

    摘要： Quartz glass element, such as a diffusion tube useful in the production of semiconductor elements, capable of forming an outer layer of uniformly fine crystalline silica such as cristobalite or tridymite when heated to a temperature at which such crystalline silica forms containing crystallization promoting nuclei having a rate of diffusion in quartz glass less than that of sodium at elevated temperatures. Such nuclei are present in the outer half of the element wall and the maximum concentration of such nuclei is at the surface of the element and then diminishes inwardly. When the quartz glass element is exposed to elevated temperatures, the nuclei promotes the formation of the outer layer of uniformly fine crystalline silica which imparts thermal dimensional stability for extended periods of use at elevated temperatures.

    摘要： A composite quartz glass body such as a hollow body, e.g., a diffusion tube or ampoule for carrying out diffusion processes for making solid state components includes an inner layer of synthetic quartz glass and an outer layer of quartz glass fused onto the inner layer from quartz crystal granules, the outer layer having a portion thereof which covers or envelops the inner layer and contains diffusion inhibitors of hydroxyl ions, divalent cations or small air bubbles.

    摘要： A tubular quartz glass body useful in carrying out diffusion processes in semiconductor technology has an inner tubular portion of high-purity synthetic quartz glass which is fused to a surrounding portion of fused quartz crystal granules or powder. Then surrounding, enveloping portion has an outer layer of finely crystalline cristobalite or in the outer surface layer thereof, crystallization promoting nuclei capable of forming an outer layer of crystalline silica. The nuclei are not semiconductor poisons and have a rate of diffusion in quartz glass less than that of sodium at elevated temperatures, such as temperatures encountered in diffusion processes which are between 1,200* and 1,380*C.
