The extent of reaction of hydrogen with various carbides, nitrides, borides, and oxides was studied in a static system. Most of these materials, HfC, ZrC, TiC, TaCs NbC, WC, Mo/sub 2/C, HfN, ZrN, NbN, ZrB/sub 2/, NbB/sub 2/, and WB, showed less reaction than the minimum detectable value. However, the data seem to indicate that the ceramics, TiN, TaN, HfB/sub 2/ TiB/sub 2/2, ZrO/ sub 2/, and Cr/sub 2/O/sub 3/, h ad reacted. Reactions of SiC, VC, and TaB/sub 2/ were not determinable because of their incompatibility with the tungsten container. (auth) 14519((((Abstract unscannable)))
