Effects of anode material on arcjet performance [PDF]

, 1992
Anodes fabricated from four different materials were tested in a modular arcjet thruster at 1 kW power level on nitrogen/hydrogen mixtures. A two-percent thoriated tungsten anode served as the control. Graphite was chosen for its ease in fabrication, but

Nonoxide ceramic interactions with uranium or carbon. [Reaction of BN, TiN, HfC, CeS, or Ce2S3 with U, C, BeO, W, or Y2O3]

, 1978
The interaction of possible nonoxide containment materials (including boron nitride, titanium nitride, hafnium carbide, and two cerium sulfides) with uranium or carbon has been examined by thermal analysis techniques.
