%X Satellites are equippedwithmicrothrusters that control their orbit and attitude. The thrust is achieved by the catalytic decompo- sition of hydrazine by iridium supported on alumina.As nitrides and carbides of molybdenum and tungsten behave like noble metals in many catalytic reactions, they were tried in a 2 newton hydrazine microthruster. Their performance was similar to that of the iridium catalyst, with respect to ignition delay and thrust. Their mechanical resistance appears higher than that of iridium-based catalyst. This application is the first practical one for nitrides and carbides of early transition metals as substitutes of noble metals, a possibility first reported in 1973.
