Abstract: Alkali aluminosilicate glasses that exhibit fast ion exchange performance and having low softening points that enable the glasses to be formed into non-planar, three-dimensional shapes. The glasses contain less than about 1 mol % of boron oxide and, in some embodiments, are substantially free of B2O3. Furthermore, these glasses have excess amounts of alkali oxides relative to both Al2O3 and P2O5, in order to improve melting behavior and ion exchange performance while still achieving sufficiently low softening points to allow for formability.

Abstract: A control system for an axial skinning apparatus (100), including: •a force to cause a ceramic honeycomb part (110) to pass through the skinning apparatus (100); •a force that urges flowable cement on to the ceramic honeycomb part (110); •a sensor to detect the force on the cement; •a sensor to detect the force on the ceramic part; and •a controller (300) which receives: •a signal from the sensor on the flowable cement, •a signal from the sensor on the ceramic part (110), or both, and the controller (300) controls the pressure set point (310) of the cement source based on one or both of the received signals, and the controller (300) adjusts control parameters using feedback control and pseudo feed forward control. A method of using the axial skinning apparatus (100) is also disclosed.
