..., refractory metals containing silver or copper contact materials are made either by pressing and sintering or by the press-sinter-infiltrate method. When infiltration is used, either all refractory metal powder is compacted to shape, or a small amount of silver or copper powder is blended with the refractory...

... and sintered at temperatures in excess of 2000 °C (3600 °F), resulting in a high-purity product. Reaction-bonded SiC, on the other hand, is processed by forming a porous shape comprised of SiC and carbon-powder particles. The shape is then infiltrated with silicon metal; the silicon metal acts to bond the SiC...

This approach is highly effective but cannot be used for some highly alloyed grades with compositions that do not permit a ferritic solidification mode. In such alloys, sulfur and other contaminants, such as phosphorus, oxygen, zinc, and copper, must...
