Pb-Sn Phase Diagram

High-purity Pb and Sn are very difficult metallographic subjects and the alloys of Pb and Sn are somewhat easier to prepare, but still rather difficult. This Poster lists our preferred preparation procedure. Vibratory polishing is essential for best results. Pollack’s reagent (100 mLwater, 10 g citric acid, 10 g ammonium molybdate) is one of the best etchants for Pband Pb-Snalloys; 2% nitalis a good etch for pure tin..
