<p>The present invention discloses a method of sintering of cemented carbide or cermet bodies lying on graphite trays. By using graphite trays coated with a covering layer of Y2O3 containing < 20 wt.% ZrO2, or corresponding volumetric amount of other refractory oxides, e.g. Al2O3 or combinations thereof, with an average thickness of > 10 νm, the life of the trays between regrindings and recoatings can be largely extended.</p> |
