Abstract: A method for producing an electrical component (1) is proposed, in which a ceramic base body (5) that contains a through-hole contact (10) and at least one metallization surface (20C) electroconductively connected to the through-hole contact is provided in a method step A). On the surface of the base body, an electrically insulating first material is arranged in layer form at least above the through-hole contact in method step B), and thereafter an electrically conductive second material is applied above through-hole contact (10) in method step C). Then a solder contact (30B) that electroconductively connects through-hole contact (10) through passivation layer (25B), which is formed from the first material by sintering, is formed by hardening in method step D).

Abstract: An electrical component includes a base body made using ceramic, metallization surfaces that at least partly define component structures on the base body, a passivation layer that is electrically insulating and over a surface of the base body, solder contacts on the passivation layer, and through-hole contacts inside the base body that are electrically connected to corresponding metallization surfaces. The solder contacts are electrically connected to corresponding through-hole contacts through the passivation layer.

Abstract: Mesoscopically ordered, hydrothermally stable metal oxide-block copolymer composite or mesoporous materials are described herein that are formed by using amphiphilic block polymers which act as structure directing agents for the metal oxide in a self-assembling system.

Abstract: A piezoelectric transformer includes a base body. The base body includes an input part and an output part mechanically connected to the input part. The base body also includes internal electrodes perpendicular to a polarization axis of the transformer-in the input part and the output part. The transformer also includes an auxiliary electrode galvanically separated from the input part and the output part.
