The disclosure relates to a bond produced with an at least partially crystallized glass, such as a metal-to-glass bond, in particular a metal-to-glass bond in a feed-through element or connecting element, and to a method for producing such a bond, in particular in a feed-through element or connecting element. The at least partially crystallized glass includes at least one crystal phase and pores which are distributed in the at least partially crystallized glass in a structured manner.

The present invention relates to a transparent sealing member. A quartz glass transparent sealing member is used in an optical component having at least one optical element, and a mounting board on which the optical element is mounted, and constitutes, with the mounting board, a package that houses the optical element. The concentration of aluminum in a surface portion is higher than the concentration of aluminum in an inner portion.

The present invention relates to a method for the automated production of a workpiece having at least one diaphragm, including a workpiece for an electrochemical sensor, including providing a workpiece that has a wall with at least one continuous opening through the wall, wherein a diaphragm body is affixed in the at least one opening, such that the diaphragm body completely fills a cross-section of the opening, and processing the diaphragm body by means of a laser.

The object of the present invention is an integrally bonded composite component, a method for the production thereof, and the use thereof. The invention particularly relates to integrally bonded transparent ceramic composite components, to a method for the production of such ceramic composite components, and to the use thereof.

Lithium silicate glass ceramics and glasses are described which can advantageously be applied to zirconium oxide ceramics in particular by pressing-on in the viscous state and form a solid bond with these.

An at least partially crystallized glass includes at least one crystal phase and pores which are distributed in the at least partially crystallized glass in a structured manner.

An improved method for embedding one or more sensors in SiC is provided. The method includes depositing a binder onto successive layers of a SiC powder feedstock to produce a dimensionally stable green body have a true-sized cavity. A sensor component is then press-fit into the true-sized cavity. Alternatively, the green body is printed around the sensor component. The assembly (the green body and the sensor component) is heated within a chemical vapor infiltration (CVI) chamber for debinding, and a precursor gas is introduced for densifying the SiC matrix material. During infiltration, the sensor component becomes bonded to the densified SiC matrix, the sensor component being selected to be thermodynamically compatible with CVI byproducts at elevated temperatures, including temperatures in excess of 1000? C.

A multilayer ceramic substrate that includes a surface layer portion positioned on an internal layer portion, and a surface layer electrode on a surface of the surface layer portion. The surface layer portion includes a first layer next to the internal layer portion, and the internal layer portion includes a second layer next to the first layer. The thermal expansion coefficient of the first layer is lower than the thermal expansion coefficient of the second layer. The first layer and the second layer each contain glass containing 40 weight % to 65 weight % of MO, where MO is at least one selected from CaO, MgO, SrO, and/or BaO); 35 weight % to 60 weight % of alumina, and 1 weight % to 10 weight % of at least one metal oxide selected from CuO and/or Ag.sub.2O.

The invention relates to a transparent composite material for various applications, having crystalline and amorphous inorganic materials with improved material properties.
