A ceramic component having a ceramic main part containing AxByC1−x−vTi1−y+wO3*(Mn2P2O7)z*Du, in which A is a first dopant selected from a group including neodymium, praseodymium, cerium, and lanthanum, B is a second dopant selected from a group including niobium, tantalum, and vanadium, C is selected from a group including calcium, strontium, and barium, and D includes a metal selected from a group including aluminum, nickel, and iron. x is the proportion of A, y is the proportion of B, v is the proportion of A vacancies, w is the proportion of excess titanium, z is the proportion of Mn2P2O7, u is the proportion of D, and the following applies: 0.0≤x<0.1, 0.0≤y<0.1, 0≤v<1.5*x, 0≤w<0.05, 0.01≤z<0.1, 0≤u<0.05. A method for producing the ceramic component is also disclosed.

Ceramic component and method for producing the ceramic component

A multilayer component and a mathod for producing a multilayer component are disclosed. In an embodiment a multilayer component includes a ceramic main element and at least one metal structure, wherein the metal structure is cosintered and wherein main element is a varistor ceramic having &#x2265;90 mol % of ZnO, from 0.5 to 5 mol % of SbO, from 0.05 to 2 mol % of CoO, MnO, SiOand/or CrO, and &#x3c;0.1 mol % of BO, AlOand/or NiO.

Multilayer component and process for producing a multilayer component

A multilayer component and a mathod for producing a multilayer component are disclosed. In an embodiment the multilayer component includes a ceramic main element being a varistor ceramic and at least one metal structure, wherein the metal structure is cosintered, and wherein the main element is doped with a material of the metal structure in such a way that a diffusion of the material from the metal structure into the main element during a sintering operation is reduced.

An electrical component includes a ceramic base body. The ceramic base body includes several ceramic layers including a function layer and a composite layer bordering the function layer. The composite layer can include a zirconium oxide-glass filler mixture.
