20160083302 | POLYCRYSTALLINE CHALCOGENIDE CERAMIC MATERIAL - The invention relates to a polycrystalline IR transparent material produced by sintering chalcogenide powder, e.g., ZnS powder, using hot uniaxial pressing followed by hot isostatic pressing. The microstructure of the material described in this disclosure is much finer than that found in material produced using the state of the art process. By using a powder with a particle size fine enough to improve sintering behavior but coarse enough to prevent a lowering of the wurtzite-sphalerite transition temperature, a highly transparent material with improved strength is created without degrading the optical properties. A high degree of transparency is achieved during hot pressing by applying pressure after the part has reached a desired temperature. This allows some degree of plastic deformation and prevents rapid grain growth which can entrap porosity. The crystallographic twins created during this process further inhibit grain growth during hot isostatic pressing. | 03-24-2016 |

20130019741 | GLASS-CERAMIC WITH LAMINATES - A transparent armor system includes a hard face fabricated from a substantially transparent glass-ceramic material exhibiting crystalline bodies throughout the mass of the glass-ceramic material and a backing covering a rear surface of the hard face opposite an anticipated incoming projectile. The backing has a refractive index substantially matching that of the hard face such as to allow substantial transparency of the transparent armor system. The hard face serves to disburse energy caused by the impact of an incoming projectile with the transparent armor system, while the backing serves to retain any pieces of the hard face fractured during ballistic impact. In certain embodiments, a plurality of hard faces are held in parallel and spaced apart arrangement. | 01-24-2013 |
