Abstract
A nonfocused infrared panel emitter and method of making the same. The panel emitter includes a primary emitter positioned between an insulating layer and a secondary emitter. Preferably, the panel emitter comprises a metal foil primary emitter, woven alumina cloth secondary emitter, and alumina silica board insulating layer bonded together by means of an alumina silica binder. In the method of making the panel emitter, a mesh sheet is preferably positioned adjacent the foil and the sheet is vaporized by heating prior to bonding to create a void adjacent the foil to allow thermal expansion and contraction of the foil.
