  • Methods of sintering dense zeta-phase tantalum carbide
    Patent number: 9896384
    Abstract: A method of forming a sintered ?-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 ?-phase with at least about 90% densification. After sintering, the tantalum carbide can be cooled to substantially retain the ?-phase.
    Type: Grant
