For the application of the material as hollow cathodes in small satellite propulsion systems, its preparation as sinterable glass-ceramics via the powder route is purposeful. The coefficient of thermal expansion CTE is between 4.2 and 6.0 × 10−6 K−1 (RT-1000°C). Fri, 01 Jan 2021 00:00:00 GMT https://fordatis.fraunhofer.de/handle/fordatis/275 2021-01-01T00:00:00Z
