The invention relates to a method for producing compression scandium disperse cathode, wherein said method dissolves the Sc (NO3)3, Ba (NO3)2, Ca (NO3)2, Al (NO3)3 and ammonium metatungstate into water to be mixed, and adds citrate solution to be bathed, to form gel, then drying it to form gel, to be decomposed to obtain powder; reducing and compressing the powder into sample; sintering it under hydrogen gas to form cathode material. The invention has better repeat property, to apply batch production. And the elements of cathode material are uniformly distributed, with better emission property under 800Deg. C. |
