Abstract:
The invention is directed to highly crystalline, frit sintered glass ceramic materials and seals made using them that are suitable for solid oxide fuel cell applications. The seals have a coefficient of thermal expansion in the range of 70-130 x 10 -7 °C, preferably 85-115 x 10 -7 °C. The glass ceramic materials have a crystalline component and a glass component, the crystalline component being >50% of the glass ceramic and the glass component being 75%. Regarding the crystalline component only, >50% of the crystals in the crystalline component of the glass ceramic has a structure selected from the structural groups represented by walstromite, cyclowollastonite, µ (Ca,Sr)SiO 3 , kalsilite, kaliophilite and wollastonite (the primary crystalline phase) and the remaining
Abstract:
The present invention relates to semiconductor-on-insulator structures having strained semiconductor layers. According to one embodiment of the invention, a semiconductor-on-insulator structure has a first layer including a semiconductor material, attached to a second layer including a glass or glass-ceramic, with the CTEs of the semiconductor and glass or glass-ceramic selected such that the first layer is under tensile strain. The present invention also relates to methods for making strained semiconductor-on-insulator layers.

Compositions, articles and methods for making such articles are disclosed. The compositions, articles and methods include calcium aluminate materials consisting essentially of a main phase of CaAl407 and having a low coefficient of thermal expansion produced by utilizing an additive and firing to temperatures below about 1600° C.
Abstract:
T This disclosure teaches the use of low density, "open" - structure glasses as backing glasses (14), behind glass - ceramic strike-faces (12), in transparent armor composite windows. These low density "open- structure 1 glasses are sometimes referred to as "anomalous" glasses. For transparent armor applications both silica, including fused silica, and borosilicate glasses can be used as backing glass. These backing glasses provide improved ballistics performance over that of standard commercial soda lime backing glass. These glasses should be used either in their as -formed state (e.g. float surfaces) or should be finished using a process designed for minimizing sub-surface damage.
Abstract:
A transparent armor laminate system is described that utilizes a glass ceramic material as the strike face material (26), one or a plurality of intermediate layers (22), and a backing material (24). This laminate system offers improved performance with reduced weight over conventional all glass or all-glass-ceramic transparent armor systems.
