Heating element for indirectly heated cathode and method for the manufacture of such an element |
| abstract |
This heating element is constituted by a filament and a mixture, fritted at between 1700° and 1800° C., of alumina and less than 10% by weight of yttrium oxide. This mixture fills the space left free by the filament within the cylinder closed by an emissive disk forming the cathode. |
