Abstract
The present invention relates to a cathode assembly employing a cermet pellet and a method for manufacturing the same. The cathode assembly of the present invention has a good quality such as a low work function and an enhanced life span as compared with the conventional cathode assembly. Also, since the method for manufacturing a cermet pellet is more simplified than that of the cermet thin film, the cathode assembly employing the cermet pellet according to the present invention can be manufactured with ease and at a low cost.
