PROCESS FOR PRODUCING A POLYCRYSTALLINE SILICON CARBIDE BODY
Method for the production of a polycrystalline shaped body of silicon carbide of a density of at least 98% of the theoretical density of silicon carbide, prepared through pressureless sintering at temperatures from 1,900 to 2,200 C. from at least 97 weight % of alpha -silicon carbide and/or beta -si...

| description | Method for the production of a polycrystalline shaped body of silicon carbide of a density of at least 98% of the theoretical density of silicon carbide, prepared through pressureless sintering at temperatures from 1,900 to 2,200 C. from at least 97 weight % of alpha -silicon carbide and/or beta -silicon carbide under addition of up to 3 weight % of boron, characterized by the fact that the shaped body is prepared without any carbon additions to the batch and is pressureless sintered in a carbon containing protective gas atmosphere. |
