APPARATUS AND METHODS FOR FABRICATING GLASS RIBBON

Abstract:

Apparatus can comprise a containment device including a surface defining a region extending in a flow direction of the containment device. A support member positioned to support a weight of the containment device can comprise a support material with a creep rate from 1.times.10.sup.-12 l/s to 1.times.10.sup.-14 l/s under a pressure of from 1 MPa to 5 MPa at a temperature of 1400.degree. C. In some embodiments, the support material can comprise a ceramic material. In some embodiments, the support material can comprise silicon carbide. In some embodiments, a platinum wall can be spaced from physically contacting any portion of the support member. In some embodiments, methods can comprise flowing the molten material within the region in the flow direction while supporting a weight of the containment device with the support member.
