Abstract

기존의 산화마그네슘, 산화알루미늄, 산화규소로 조성되는 세라믹 분말에 산화철이 0. 01∼0. 7% 이하로 함유되고 내화도가 S. K16번(1460℃)전후인 세라믹분말이나, 이들 성분과 유사한 성분을 갖는 카오린, 탈크, 산화알루미늄을 분말화하여 철분을 자력으로 제거한 것에유기바인더로서 P. V. A스테아린산등을 첨가하여관용되는 방법.으로 탄산가스 편면 용접용 세락믹을 제조함으로서 고전압, 고전류하에서 내기공성이 뛰어나고, 박리성저하, 스파타, 오버랩, 언더컷 등이 발생하지 않는 특징이 있는 것이다.A ceramic powder composed of conventional magnesium oxide, aluminum oxide and silicon oxide has an iron oxide content of 0.01-0. Ceramic powder having a refractivity of about 7% or less and having a refractivity of about S.K16 (1460 DEG C), or kaolin, talc, and aluminum oxide having components similar to those components were powdered and iron powder was removed by magnetic force. Stearic acid or the like to produce a carbonic acid gas single-side welding ceramics, which is excellent in porosity under high voltage and high current, and does not cause deterioration in peelability, spatter, overlap, undercut, etc.
