<p>Disclosed is a process for preparing a cathode structure for impregnated cathodes having desired dimensions by a simplified process without experiencing machining etc. A high-melting-point metal powder (eg. tungsten) is introduced into a mould, and heated with the heater to effect isostatic hot press moulding to provide a cathode structure for impregnated cathodes having a predetermined shape and dimensions by one operation.</p> |
