Glasses having a low softening point and high toughness. The glasses are alkali aluminoborosilicate glasses having softening points of less than 900° C. and, in some embodiments, in a range from about 650° C. up to about 825° C., and an indenter damage threshold of at least 300 g for glasses that are not chemically strengthened. The glasses are free of alkaline earth metals, lead, arsenic, antimony, and, in some embodiments, lithium.

摘要:
A reactive-ceramming process for making YPO4 ceramics involving the reaction between a YP-glass and a Y-source material. The invention can be used to synthesize, inter alia, phase-pure YPO4 ceramic material 5 at a relatively low temperature in a relatively short period of time and at a low cost. Invention can be used to make large piece of YPO4 blocks suitable for, e.g., an isopipe in a fusion down-draw process for making large-size glass sheets.
摘要:
Photovoltaic devices having light scattering articles having a smooth surface are described herein. Glass frits on glass superstrates can provide planar surfaces for subsequent layer deposition such as TCO layers and yet provide light scattering functions within, for example, silicon tandem photovoltaic devices. Methods of making the light scattering articles with a planar surface include depositing unfilled or filled glass frits on planar or surface-textured superstrates and sintering of the glass frit. The compositions of the glass frits can be tailored to match, for example, the expansion properties and physical properties of the glass superstrates.
