| 20080287278 | LOW LOSS CHALCOGENIDE GLASS AND PROCESS FOR MAKING SAME USING ARSENIC MONOCHALCOGENIDE - This invention pertains to a chalcogenide glass of low optical loss that can be on the order of 30 dB/km or lower, and to a process for preparing the chalcogenide glass. The process includes the steps of optionally preparing arsenic monochalcogenide precursor or the precursor can be provided beforehand; dynamically distilling the precursor in an open system under vacuum from a hot section to a cold section to purify same; homogenizing the precursor in a closed system so that it is of a uniform color; disposing the distilled or purified precursor and at least one chalcogenide element at a hot section of an open distillation system; dynamically distilling under vacuum in an open system so that the precursor and the at least one chalcogenide element are deposited at a cold section of the open system in a more purified state; homogenizing the precursor and the at least chalcogenide element in a closed system while converting the precursor and the at least one chalcogenide element from crystalline phase to glassy phase. | 11-20-2008 |
| 20090270241 | Ga-P-S glass compositions - Ga—P—S glass compositions that may have application in infrared (IR) windows, waveguiding fibers, or as host glasses for luminescent dopants are described. | 10-29-2009 |
| 20100022378 | MANUFACTURING PROCESS FOR CHALCOGENIDE GLASSES - The present invention is generally directed to a method of making chalcogenide glasses including holding the melt in a vertical furnace to promote homogenization and mixing; slow cooling the melt at less than 10° C. per minute; and sequentially quenching the melt from the top down in a controlled manner. Additionally, the present invention provides for the materials produced by such method. The present invention is also directed to a process for removing oxygen and hydrogen impurities from chalcogenide glass components using dynamic distillation. | 01-28-2010 |
| 20100285946 | INFRARED TRANSMITTING GLASS FOR MOLD FORMING - The purpose of the present invention is to use chalcogenide glass to produce an infrared transmitting glass that is more suitable for mold-forming than the conventional glasses. Specifically, the invention provides an infrared transmitting glass for mold forming which contains, in molar concentrations, 2-22% of Ge, 6-34% of at least one element selected from the group consisting of Sb and Bi, 1-20% of at least one element selected from the group consisting of Sn and Zn and 58-70% of at least one element chosen from the group comprising S, Se and Te. | 11-11-2010 |
| 20120135850 | PERGALLOUS ALKALINE EARTH SELENOGERMANATE GLASSES - IR-transmitting alkaline earth selenogallo- and/or selenoindo-germanate glasses that are capable of hosting luminescent rare earth dopants. The relatively high Ga and/or In content of most compositions serves to eliminate the typical clustering tendency of rare earth dopants in chalcogenide glasses, resulting in improved luminescence. | 05-31-2012 |
| 20120238432 | MANUFACTURING PROCESS FOR CHALCOGENIDE GLASSES - The present invention is generally directed to a method of making chalcogenide glasses including holding the melt in a vertical furnace to promote homogenization and mixing; slow cooling the melt at less than 10° C. per minute; and sequentially quenching the melt from the top down in a controlled manner. Additionally, the present invention provides for the materials produced by such method. The present invention is also directed to a process for removing oxygen and hydrogen impurities from chalcogenide glass components using dynamic distillation. | 09-20-2012 |
| 20150038314 | CHALCOGENIDE GLASS - Boron-containing network sulfide glass which may be useful in IR transmitting applications, such as IR optics, laser or fiber amplifiers doped with rare earths with emission in the near IR, and methods of making the same. | 02-05-2015 |
| 20150329410 | ALKALI SELENOGERMANATE GLASSES - Selenogermanate, selenogallo- or selenoindo-germanate glasses that are modified by alkali metals, for example, Na or Li and, as such, are characterized by high alkali ion mobility or conductivity. Ionic conducting chalcogenide glasses have potential application as an electrolyte medium for solid state batteries. | 11-19-2015 |
| 20150344342 | Striae-Free Chalcogenide Glasses - A method to synthesize striae-free chalcogenide glass using melt processing. A striae-free chalcogenide glass with uniform refractive index. | 12-03-2015 |
