TECHNOLOGY FOCUS - CERAMICS AND GLASS - Preferred Process: The step of laminating together under pressure comprises laminating in a hydrostatic pressure laminator at a pressure sufficient to cross-link the organic binder in the wraps and form linked polymer molecular chains between wraps. The fabrication of ceramic tube further includes wrapping green ceramic material around the mandrel over at least one of the second or the third tubular surface at end regions (1c1) of the tube only and not at a central region of the tube, placing a releasing agent on the surface of the mandrel before wrapping, and wrapping a sacrificial organic material around the mandrel to a desired thickness before wrapping the first electrode material.The separation of mandrel from the laminated wraps comprises activating the releasing agent on the surface of the mandrel, and withdrawing the mandrel from the laminated wraps. The placing of the releasing agent on the surface of the mandrel comprises applying wax to the surface of the mandrel. The activation of releasing agent comprises melting the wax.Preferred Component: The wrapped green ceramic material is tape material, and is wound around the mandrel in a spiral pattern. It is wound around the mandrel in spirals of complimentary right-hand and left-hand twist one wound layer to the next. The first electrode material or the second electrode material is metal, or electronically conductive green ceramic. The green ceramic material and electronically conductive green ceramic contain a cross-linkable organic binder. The first electrode material or second electrode material is a composite of a green ceramic and a conductive metal in an amount sufficient to render the composite conductive. The composite comprises a matrix of the green ceramic, and particles of the conductive metal are dispersed in the matrix.Preferred Composition: The conductive metal particles comprise 40-90% of the composite.Preferred Property: The wrapping of the green ceramic material is to a cumulative wall thickness Ttube less than 1 mm, preferably less than 100microns.
