Abstract : Lithium aluminosilicate, when heated from 1000C to 1350C, emits lithium ions from its surface. This study evaluates beta (lithium aluminosilicate) eucryptite as an ion-emitting source. Coated refractory emitters have demonstrated an ion-emitter work function of 2.12V with a corresponding Richardson A value of 0.0084. (Author)
