| Zusammenfassung: | The present invention provides a process for producing a ceramic material, which comprises: (a) forming a green compact by compacting a powder comprising alumina and carbon, wherein the powder is substantially free of silicon carbide and wherein the amount of carbon present in the powder does not exceed 0.1% by weight of the powder; and (b) sintering the green compact under non-oxidising conditions to form a ceramic material comprising alumina and carbon, wherein the green compact is sintered at a temperature of less than 1550° C. Ceramic materials obtainable by said process are also provided. |
