The cathode subassembly is comprises (a) a porous cathode pellet (11) formed by a sintered body containing Ni, scandium oxide (Sc 2 O 3 ), and an electron-emissive material; the body being made by sintering a mixture of a Ni powder, a scandium oxide (Sc 2 O 3 ) powder, and an electron-emissive material powder using a HIP process; the pellet having an electron emission surface; and (b) a pellet support (12) for supporting the pellet; the support having a part in contact with the pellet; the part being made of an alloy containing Ni as its main ingredient and at least one metal selected from the group consisting of chromium (Cr), tantalum (Ta), molybdenum (Mo), zirconium (Zr), tungsten (W), and cobalt (Co); the at least one metal selected from the group consisting of Cr, Ta, Mo, Zr, W, and Co serving as a reducing agent for the electron-emissive material. Preferably, the electron-emissive material is a carbonate generated by co-precipitation of Ba, Sr, and Ca.

摘要： In a method of forming a coating on an electron emitting cathode, in which a black coating (23) is formed on the inner surface of a cathode sleeve (15) constituting the electron emitting cathode, the cathode sleeve (15) is filled with a suspension as a coating material, and a porous absorbent member is brought into contact with or near an opening portion of the cathode sleeve at the same time or after the cathode sleeve (15) is filled with the suspension, thereby causing the porous absorbent member to absorb an unnecessary portion of the suspension. Thereafter, the cathode sleeve (15) to which the coating material is adhered is heat-treated. As a result, a black coating (23) having a uniform thickness is formed, on the inner surface of the cathode sleeve, as a sintered layer obtained by mixing tungsten having an average particle diameter in a range of 0.5 µm (inclusive) to 2 µm (inclusive) with alumina having an average particle diameter in a range of 0.1 µm (inclusive) to 1 µm (exclusive) at a weight ratio of the tungsten to the alumina in a range of (90 : 10) to (65 : 35).

摘要： An electron gun cathode (104) is column shaped, and emits electrons by being heated. A holder (103), which covers the bottom and sides of the electron gun cathode, has electrical conductivity and holds the electron gun cathode, and is composed of a material that does not easily react with the electron gun cathode when in a heated state, is provided. The tip of the electron gun cathode (104) protrudes from the holder (103) so as to be exposed, and electrons are emitted from the tip toward the front by applying an electric field to the tip.

摘要： There were problems with the conventional cathode for electronic tubes such as: metals that composing the substrate were subjected to heat deformation resulting in a relatively large drift of cutoff voltage. It is the object of the present invention to solve this problem by diminishing the heat deformation of the substrate to obtain a cathode with a small drift of cutoff voltage.
Heat expansion coefficients can be made uniform while metals in the metal layer are prevented from diffusing into the substrate by incorporating the same metals as in the metal layer on the substrate into the metals composing the substrate, thereby suppressing deformation of the substrate.
