Composite materials and bodies including silicon carbide and titanium diboride and methods of forming same

Patent Lillo, Thomas M. ; Chu, Henry S. ; Harrison, William M. ; Bailey, Derek

Methods of forming composite materials include coating particles of titanium dioxide with a substance including boron (e.g., boron carbide) and a substance including carbon, and reacting the titanium dioxide with the substance including boron and the substance including carbon to form titanium diboride. The methods may be used to form ceramic composite bodies and materials, such as, for example, a ceramic composite body or material including silicon carbide and titanium diboride. Such bodies and materials may be used as armor bodies and armor materials. Such methods may include forming a green body and sintering the green body to a desirablemore »« less
