Ceramic powder containing 0.01 ~ 0.7% or less of iron oxide in the ceramic powder composed of magnesium oxide, aluminum oxide, and silicon oxide and having a fire resistance of about SK 16 (1,460 ° C), or kaolin having a similar component to these components, Talc, aluminum oxide powdered to remove iron by magnetic force, PVA as organic binder By producing a ceramic for welding carbon dioxide single-sided welding by adding a stearic acid or the like, it is excellent in porosity resistance under high voltage and high current, and does not cause peeling degradation, spatter, overlap, undercut, or the like. |
