Abstract:
Refractory materials are provided which contain P 2 O 5 /R 2 O 3 constituents, where R is Y, Sc, Er, Lu, Yb, Tm, Ho, Dy, Tb, Gd, or a combination thereof, and/or V 2 O 5 /R' 2 O 3 constituents where R' is Y, Sc, one or more rare earth elements, or a combination thereof. In certain embodiments, the refractory materials are xenotime-type materials and/or xenotime-stabilized zircon-type materials. The refractory materials can be used in the manufacture of glass and glass-ceramics. For example, the refractory materials, especially those that contain P 2 O 5 /R 2 O 3 constituents, can be used as forming structures ("isopipes") in the fusion process for making flat sheets of glass such as the glass sheets used as substrates in the manufacture of flat panel displays.

Abstract:
A pull roll assembly is described herein that is used to draw a glass sheet. The pull roll assembly includes a first roll assembly, a second roll assembly and a device (e.g., differential drive, sensor(s)). The device enables one to control the first and/or second roll assemblies based in part on pulling forces (e.g., glass contact normal force and/or required sheet pulling force) associated with a glass sheet while the glass sheet is being drawn between the first and second roll assemblies. A glass manufacturing system and method for using the pull roll assembly are also described herein.

Abstract:
Disclosed are systems and methods for forming glass sheets. Methods and systems are provided that comprise a refractory body configured to receive glass-based material and means for transmitting energy to selectively heat at least a portion of the refractory body through the glass-based material. In one aspect, the energy transmitted is of a selected frequency that is not fully absorbed by the glass-based material and is at least partially absorbed by the refractory body. The energy can be transmitted by a laser beam array, a scanning laser beam, a microwave generator, a radio frequency generator, or other means.
