Abstract: A method for forming and shaping powder mixtures involves compounding, homogenizing, and plasticizing components to form a mixture. The components are powder materials, binder, solvent for the binder, surfactant, and non-solvent with respect to at least the binder, the solvent, and the powder materials. The non-solvent is lower in viscosity than the binder combined with the solvent. The components are chosen to result in improved wet green strength in the subsequently formed green body. The compounding is done by the steps of dry-mixing the powder material, surfactant and binder to form a uniform blend, adding the solvent to the resulting dry blend, and thereafter adding the non-solvent to the blend. The mixture is shaped by passing it through a low to moderate shear extruder, and then through a die to form a green body. The compounding and shaping steps are carried out at a temperature of no greater than ambient temperature. The method is especially suitable for RAM extrusion. Among the advantages, the method results in higher extrusion velocity, throughputs, and wet green strength, without increasing pressures and torques.

Abstract: An isopipe (13) for forming a glass ribbon (19) by a fusion process is provided which comprises a trough (11) and first and second weirs (1,2). Each weir (1,2) has an aperture (35) that extends along at least part of the weir's length. The apertures (35) can be used to cool the interior of the weirs (1,2) and thus reduce their creep rate. Alternatively, the apertures (35) can include structural members (41,42) to stabilize the weirs. In certain embodiments, the structural members (41,42) do not completely fill the apertures (35) thus allowing for weir stabilization through a combination of mechanical support and internal temperature reduction.

Abstract: A method of forming an oxide glass including heating a glass melt having a -OH concentration of at least about 0.35 in a vessel comprising a metal selected from the group consisting of platinum, molybdenum, palladium, rhodium, and alloys thereof, there being an interface present between the vessel and the glass, and controlling a partial pressure of hydrogen in an atmosphere in contact with an outside surface of the vessel in an amount such that hydrogen permeation blisters form in a region of the glass adjacent the glass-vessel interface.
