摘要： A ceramic product includes a first ceramic part and a second ceramic part, wherein the first ceramic part is connected with the second ceramic part via a joint, wherein the joint comprises an active hard solder, or braze, characterized in that the joint has an inhomogeneous distribution of the components of the active hard solder, or braze, wherein at least at an interface between the active hard solder, or braze, and the ceramic, the at least one active component of the active hard solder, or braze, is enriched. For manufacture of the product, the active hard solder, or braze, material is provided in such a manner, that at least one surface section of at least one of the ceramic parts is first coated with at least one active component of the active hard solder, or braze, and that on the coated section, an alloy is provided, which, by melting of the alloy during the heating, alloys with the coating and forms a metal joint between the two ceramic parts.

摘要： A method for manufacturing an elastic deformation body made of an Al2O3 ceramic according to which a highly pure alumina having at most 2000 ppm MgO, at most 200 ppm inorganic impurities, a specific surface of at least 10 m2/g, an average grain size of at most 0.3 μm is applied. With the alumina and additives, there is produced via aqueous processing a homogeneous mixture, from which a pressable spray granulate is produced, which is formed by means of a uniaxial pressing method to a homogeneous, green body, which is subjected to a sinter process. The resulting elastic deformation body has a bending fracture stress σc, whose distribution F(σc) is given by the Weibull parameters σ0≧800 MPa and m≧24, with an average grain size of the sintered material of no more than 2 μm, and wherein the sintered material of the deformation body has a density of not less than 3.98 g/cm3.
