Abstract

A green ceramic body, in particular a green ceramic film having a function layer which contains platinum and is applied in at least some areas is described; this function layer is photostructurable in daylight and in the presence of oxygen. In addition, a method of producing such a green ceramic body is described, including the process steps: a) making available a green ceramic starting body, b) applying a photostructurable paste containing platinum to the starting body in at least some areas, in particular by printing, in daylight and in the presence of oxygen, and c) photostructuring the applied paste to form the function layer. The green ceramic body described here is suitable in particular for further processing to form a temperature sensor.
