Abstract: A hydrogen occluded alloy and a process for producing the above alloy are disclosed. The process mechanically forms the hydrogen occluded alloy having improved initial discharging characteristics. In the above process, either a powdered LaNi5 alloy or rare earth metals, such as La, Ce, Pr and Nd, or a powdered CaCu5 alloy of Mm-Mn-Ni-Al-Co is mixed with a powdered Laves alloy of Zr-Mn-V-Cr-Ni alloys into a powdered alloy mixture. Thereafter, the alloy mixture is subjected to mechanical impact by a high energy ball mill with an attritor, thereby mechanically forming the hydrogen occluded alloy. The above process easily controls the manganese component while producing the hydrogen occluded alloy through the mechanical alloying.

Abstract: PROBLEM TO BE SOLVED: To reduce a cost by shortening of a process, improve an evaporation characteristic, and lengthen the service life. SOLUTION: A cathode which has a metallic cap 5 and a cathode sleeve 3 to surround a heater 1 and in which a surface of the metallic cap 5 is coated with a thermion emitting material layer 9 containing alkaline earth metal mainly composed of barium, is provided. The layer 9 containing alkaline earth metal mainly composed of this barium is composed of solid solution-like (barium- strontium-calcium) titanate of alkaline earth metal such as barium, strontium and calcium.
