Abstract
The invention relates to a method for soldering a metal electrode to an electrically conductive silicon carbide ceramic element and to a silicon carbide ceramic element made in accordance with the method. Silicon is used as the solder which provides a good electrical connection and, as the solder has approximately the same coefficient of expansion as the ceramic element mechanical stress due to temperature changes is minimized.
