Quality and Performance of Commercial Nanocomposite Scandate Tungsten Material

Nano-composite scandate tungsten cathodes have been demonstrated to have superior performance to other thermionic cathodes by researchers worldwide. Focus on quality and its relationship to emission performance is essential for transferring this transformational material technology to commercial applications. Metrics for evaluation of powder quality, sintered pellet quality, and emission performance have been established and are employed for manufacture of commercially viable large batch scale production process.
