Some generalizations about the response of zirconium to several key species in geothermal fluids are made in this paper. These species include hydrogen ion (pH), chloride ion, sulfur and its compounds, carbon dioxide, ammonia fluoride ion, and heavy metal ions. Emphasis is on zirconium’s resistance to pitting, crevice corrosion and stress corrosion cracking to these species. Results of U-bends and crevice corrosion tests show that zirconium has excellent corrosion properties in 25% NaCl + 0.5% CH3COOH + 0.1% S + saturated H2S with or without saturated CO2.
