Abstract
A ceramic component is provided, including a ceramic body containing silicon carbide, and an oxide layer provided on the ceramic body, the oxide layer being formed by oxidizing the ceramic body in the presence of alumina having a submicron particle size.
Claims11
A method of forming a ceramic component, comprising:
- providing a ceramic body comprising silicon carbide;
- providing alumina in contact with the ceramic body, the alumina having a particle size less than 1.0 micron;
- and
- oxidizing the ceramic body.
1 more element
A method of processing ceramic parts, comprising:
- providing ceramic parts and at least one refractory component in a furnace, the refractory component comprising a ceramic body comprising silicon carbide, and an oxide layer, the oxide layer being formed by oxidizing the ceramic body in the presence of alumina having a submicron particle size;
- and
- heat treating the ceramic parts and the at least one refractory component at a temperature not greater than 1500° C. and for a time period not less than about 1 hour.
