溶胶-凝胶法制备W-Ir混合金属基阴极
Preparation of W-Ir mixed metal-based cathode by Sol-Gel method
摘要
Abstract
Because the general mixed metal matrix cathode can't meet emission performance needs, the research focus on the W-Ir mixed metal-based cathode made with Sol-Gel method. The composition, microgram and granularity of the power and the surface and inner of the mixed metal-based cathode are studied by XRD and SEM. The emission performance of the mixed metal-based cathode has been measured. And the influence of activation temperature and time on the emission performance has been studied. The results show that the surface and inner structure and the emission performance of the mixed metal-based cathode made with Sol-Gel method are all better than the general mixed metal matrix cathode made with solid-liquid doping.关键词
