    摘要： The disclosure relates to methods for forming pre-melting and/or melting glass batch materials comprising bringing glass batch materials into contact with a plasma plume for a residence time sufficient to form substantially homogeneous, spheroid-shaped glass intermediate particles. The glass batch materials may flow in a cyclonic pattern in the plasma plume for increased residence time. The glass intermediate particles may be cooled with a tangential flow of gas to produce a cyclonic flow within the collection vessel. Also disclosed herein are glass intermediate particles comprising at least about 45 wt % of alumina and/or silica and less than about 55 wt % of at least one oxide of boron, V magnesium, calcium, sodium, strontium, tin, and/or titanium, wherein the glass intermediate particles are substantially homogenous and substantially spheroid in shape and have an average particle size ranging from about 5 to about 1,000 microns.

    摘要： An apparatus (10) for forming the outer layers of a glass laminate sheet comprises a reservoir (12), individual first (14a) and second (14b) distributors extending below and in fluid communication with the reservoir, and first (30a) and second (30b) slots positioned respectively at the bottom of the first and second distributors. The slots have a length, the distributors have sides and a middle, and the length of the slots on the sides of the distributors is desirably decreased relative to the length of the slots in the middle of the distributors. The apparatus is useful with a trough or isopipe (100) to provide clad glass streams to contact an over-flowing core glass on respective sides of the trough or isopipe.

    摘要： Methods of fabricating a glass laminate is provided. According to one embodiment, a glass laminate comprised of a microwave absorbing layer and a microwave transparent layer is formed. The microwave absorbing layer is characterized by a microwave loss tangent δH that is at least a half order of magnitude larger than a loss tangent δLof the microwave transparent layer. An area of the glass laminate is exposed to microwave radiation. The exposed area comprises a cross-laminate hot zone having a cross-laminate hot zone temperature profile. Substantially all microwave absorbing layer portions of the hot zone temperature profile and substantially all microwave transparent layer portions of the hot zone temperature profile reside above the glass transition temperature TG of the various layers of the glass laminate prior to impingement by the microwave radiation. In accordance with another embodiment, a method of fabricating a glass laminate is provided where the exposed area of the glass laminate is characterized by a viscosity below approximately 1×104 poise.
