A sintering device having a die lining of increased thickness

A device having a sintering chamber, the sintering chamber being bordered by the following device parts:

• i. a first punch surface of a first punch;
• ii. a second punch surface of a second punch;
• and
• iii. an interior surface of a die;
• wherein
• the punches are adapted and arranged to apply a pressure of at least 1 MPa along a compression axis to a target in the sintering chamber;
• the first punch and the second punch are connected to an electrical power source adapted and arranged to provide a current of at least 5 kA;
• the first and second punches comprise at least 50 wt. % carbon, based on the total weight of the punch;
• the sintering chamber has a cross-sectional width W perpendicular to the compression axis of at least 300 mm;
• wherein a layer δ of a carbon material Cδ is present at at least part of the interior surface of the die, the δ having a mean thickness Dδ determined over the interior surface of the die,
• wherein Dδ is in the range from 1.1 to 8 mm.
