Abstract
-Al2O3 powdered material could be prepared from the mixtures of Li2CO3, Na2CO3 and Al2O3, which were obtained by dry mixing, wet mix-screening or spray-drying process, by stepped calculating without grinding. The effect of preparation condition on the properties of the powdered material was showed. The powder composed of /′′-Al2O3 in principle, f(′′)>70%, could be fabricated into solid electrolytic coating for metal pipeline in atmosphere, with some binders and solvents.The powder in the coating was stable chemically and electrochemically to metal, binders and moistur. The polarization behavior of cathode for “Beta-coating” showed that there was a flat at the polarization curve, which could be evaluated for the cathode protection of metal in atmosphere.关键词
