Abstract
A method of forming a sintered ζ-phase tantalum carbide can include assembling a particulate mixture including a tantalum hydride powder and a carbon source powder. The particulate mixture can be sintered to form a tantalum carbide having at least 70 wt. % of a ζ-phase with at least about 90% densification. After sintering, the tantalum carbide can be cooled to substantially retain the ζ-phase.
