Accordingly, an object of this invention is to provide a new ceramic composite material. Another object of this invention is to provide a new ceramic composite material that is strong. A further object of this invention is to provide a new ceramic composite material that is very hard. Yet another object of this invention is to provide a new ceramic composite material that is resistant to oxidation. These and other objects of this invention are achieved by providing a ceramic composite material comprising from about 5 to about 35 volume percent of a reinforcing material that is alumina (Al2O3), silicon carbide (SiC), or mixtures thereof; and a ceramic material that is based on a solid solution comprising from more than zero to less than 100 mole percent of CrB2 with the remainder in the solid solution being NbB2.
