Abstract
A ceramic composite can include a first ceramic phase and a second ceramic phase. The first ceramic phase can include a silicon carbide. The second phase can include a boron carbide. In an embodiment, the silicon carbide in the first ceramic phase can have a grain size in a range of 0.8 to 200 microns. The first phase, the second phase, or both can further include a carbon. In another embodiment, at least one of the first ceramic phase and the second ceramic phase can have a median minimum width of at least 5 microns.
Claims20
A ceramic composite comprising:
- a first ceramic phase comprising a first ceramic material;
- and
- a second ceramic phase comprising a second ceramic material;
- wherein the first ceramic material has a different composition than the second ceramic material;
- wherein at least one of the first ceramic phase and the second ceramic phase has a median minimum width of at least 5 microns.
A ceramic composite comprising:
- a first phase comprising a silicon carbide having an average grain size in a range of 0.3 to 200 microns and a carbon having an average grain size in a range of 0.5 to 100 microns;
- and
- a second phase comprising a boron carbide, and a carbon having an average grain size in range of 0.5 to 100 microns;
- wherein the silicon carbide of the first phase is separated from the silicon carbide of the second phase.
