Methods for producing glass articles from laminated glass tubing include introducing the glass tubing to a converter. The glass tubing includes a core layer under tensile stress, an outer clad layer under, and an inner clad layer. The methods include forming a feature the glass article at a working end of the laminated glass tubing and separating a glass article from the working end of the laminated glass tubing, which may expose the core layer under tensile stress at the working end of the glass tubing. The method further comprises remediating the exposed portion of the core layer by completely enclosing the core layer in a clad layer. Systems for re-cladding the exposed portion of the core layer as well as glass articles made using the systems and methods are also disclosed.

A ceramic body is prepared that includes an inner electrode disposed inside the ceramic body and in which an end portion of the inner electrode is led to a surface of the ceramic body. An electrode layer is formed on the surface of the ceramic body so as to cover the end portion of the inner electrode, the electrode layer containing a resin, a first metal filler that contains a first metal component, and a second metal filler that contains a second metal component having a higher melting point than the first metal component. A heating step of heating the electrode layer is performed to form an electrode including a metal layer that is located on the surface of the ceramic body and that contains the first and second metal components and a metal contained in the inner electrode.

A method for making a thin ceramic part involves making a casting slurry including a ceramic powder, a solvent, a binder, a plasticizer, and a dispersant. The casting slurry is tape casted to achieve a single layer green tape. At least two single layer green tapes are laminated to form a green tape lamination. The green tape lamination is dry pressed, dried, shaped, degreased, and fired to achieve the exterior component required.

According to the state of the art, piezoceramic multi-layer elements are sintered in air at temperatures of approximately 1100 DEG C or higher. Therefore, only a noble metal having a high melting temperature can be used as the inner electrode. Non-noble metals would oxidize. Therefore, a silver-palladium alloy having up to 40% palladium is normally used. However, such a measure is associated with high material costs. Lower melting temperatures of the inner electrode material, however, also require a ceramic material having correspondingly low sintering temperatures. The invention therefore proposes that an electrically non-conductive sintering additive added be added to the base material, and that the inner electrode comprise silver, preferably pure silver, as the main material component thereof, and an electrically non-conductive material component and/or a metal alloy or metal oxide mixture.

The present invention provides a ceramic green sheet with a thin flat plate shape obtained by molding and solidifying a ceramic slurry, which contains a ceramic powder, dispersion medium, and gelling agent, into a thin flat plate. The ceramic green sheet partially includes a body that is obtained by molding and solidifying a conductor paste, which becomes a conductor later, and the body is exposed on a part of each of the both surfaces of the sheet. Plural ceramic green sheets described above are produced. The plural ceramic green sheets are successively stacked and press-bonded in the thickness direction in such a manner that the bodies included in the respective sheets are connected to each other for all combinations of the adjacent two sheets. As a result, a ceramic green sheet laminate is formed, which includes one body that is obtained by connecting the bodies included in the respective sheets.
