SINTERING UNIT AND METHOD FOR SPARK-PLASMA SINTERING

摘要

The sintering unit serves for the spark-plasma sintering of electrically conductive materials. The sintering unit has a sintering chamber and also a first contact and a second contact, wherein the first contact and the second contact are arranged for conducting sintering current along a sintering current path leading through the sintering chamber during the filling of the sintering chamber with electrically conductive material. In the sintering unit according to the invention, a heat-insulating element that forms a thermal insulator and an electrical conductor is arranged on a portion of the sintering current path running from the first contact to the sintering chamber and such an element is arranged on a portion of the sintering current path running from the second contact to the sintering chamber.
