    摘要: A compositional range of manganese aluminosilicate glass-ceramics with high durability, and methods for making the same, are described herein. The glass-ceramics can be used in conjunction with electronic devices, such as in protective exteriors for such devices. The glass-ceramics can be characterized as having ring-on-ring strengths of at least 300 MPa and fracture toughnesses of at least 1.5 MPa•m 1/2 .

    摘要: The invention relates to a melt-formed, high-silver, alkali-free, borosilicate glass that can be used for fabricating optical devices. For gradient index lenses, the glass can be subjected to an ion exchange process in order to introduce a less polarizable ion onto the glass surface having a higher refractive index on the surface relative to the center of the glass. The glass is unique in that the silver ions are not introduced by ion exchange. Rather, the high silver content of the glass is achieved during melting. As melted, the transparent alkali-free, borosilicate glass produced by the inventive method contains a high concentration of silver, exhibits a high refractive index and negligible attenuation at wavelengths longer than about 400 nm, making it particularly suitable for high performance fiber optic components such as gradient index or so-called GRIN lenses.

    摘要: These glasses incorporate a combination of F and Al2O3 to achieve even wider fluorescence and improved gain flatness. In addition, SPCVD incorporates large amounts of N into low-loss fiber whose high charge has an impact on rare earth behavior. The Surface Plasma Chemical Vapor Deposition (SPCVD) produces fiber preforms with high levels of F, Al2O3, and N. These heavily fluorinated glasses provide much broader Er emission than Type I or Type II silica for enhanced multichannel amplifiers. SPCVD successfully fluorinates silica with losses below 5 dB/km and increased Er emission width.

    摘要: The present invention relates to glass-ceramic/ silver composite precursor compositions in the form of powders, and to glass-ceramics/ silver composite materials produced therefrom. Such materials find particular use as interconnect materials for high temperature electrochemical conversion devices such as solid oxide fuel cells (SOFCs) and solid oxide electrolysis cells (SOECs).
