STUDIES ON STAINLESS STEEL AND ALUMINUM SLUDGES FROM NITRIC ACID CONTAINERS

Abstract

Chemical, X-ray, and spectrographic analyses show that the insoluble corrosion product of aluminum infuming nitric acid is Al(NO3)3.6H2O, and that the insoluble corrosion product of stainless steel containing columbium is a mixture of columbian carbide, silicon carbide, and anhydrous nickel nitrate. In another type of stainless, silicon dioxide and anhydrous nickel nitrate are the insoluble products. The maximum solubility of the aluminum nitrate hexahydrate in ordinary white or red fuming nitric acids is about 0.1 % at room temperature.
