Abstract
A process for the production of an insulating component from a ceramic material for a high temperature fuel cell includes the following steps: In a first step, a ceramic material is converted into a dispersion by wet preparation with a water-soluble binder. In a second step, the dispersion is poured to form a water-containing layer. In a third step, the water-containing layer is converted at elevated temperature to form a rubbery layer. In a fourth step, the binder is burnt off from the rubbery layer at elevated temperature. In a fifth step, the layer from which the binder has been burnt off is set at elevated temperature. In a sixth and a seventh step, the layer which has been set is processed in accordance with the dimensions of the insulating component and consolidated by sintering.
