Ceramic Corrosion Resistance to Sulfuric Acid

The silica and the high-alumina samples had the best acid-resistance properties. Total ions leached and sample weight loss values were generally highest at exposures of 30 to 50 wt pct H2SO4 at 90° C for the acidproof materials and at 10 wt pct H2SO4 for the acid-resistant materials.

Selection of stainless steels for handling sulphuric acid ...

Aeration or the presence of oxidising 'agents' in sulphuric acid contributes to the corrosion resistance of stainless steels. Stainless Steels have lower resistance to de-aerated sulphuric acid. Reducible ions such as Fe3+, Cu2+, Sn4+ are effectively oxidising agents and can reduce corrosion if present in the acid.
