3원 탄산염의 소정조성의 질산염을 녹인 수용액에 탄산이온을 함유하는 침전제를 가하면 3원 탄산염의 고용체 상태로 침전케하여 3원 탄산염 고용체 분말을 얻어 이 분말과 접착제 및 유기용매를 소정비율로 혼합하고, 볼밀공정으로 분산시켜 탄산염 현탁액을 만든 후 스프레이나 전착 등으로 기체 금속위에 도포하여 완성되는 산화물 음극의 제조방법에 있어서, 상기의 공정에서 3원 탄산염의 질산염과 제4물질의 질산염을 0.1-20중량% 공침 시킨 다음, 통상의 방법으로 제조함을 특징으로 하는 산화물 음극의 제조방법.When a precipitant containing carbonate ion is added to an aqueous solution of nitrates of a predetermined composition of ternary carbonate, precipitated in solid solution state of ternary carbonate to obtain ternary carbonate solid solution powder, and the powder, adhesive and organic solvent are mixed at a predetermined ratio. In the manufacturing method of the oxide cathode which is completed by dispersing in a ball mill process to form a carbonate suspension and then applying it onto a gas metal by spraying or electrodeposition, the nitrate of the ternary carbonate and the nitrate of the fourth substance are 0.1-20 in the above process. Method of producing an oxide cathode, characterized in that the coprecipitation by weight, and then prepared by a conventional method. 제1항에 있어서, 제4물질로 스칸듐(Sc), 이트륨(Y), 세륨(Ce)을 사용함을 특징으로하는 산화물 음극의 제조방법.The method of claim 1, wherein scandium (Sc), yttrium (Y), cerium (Ce) is used as the fourth material. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
