75 ml Low Form Zirconium Crucible

Zirconium exhibits superb corrosion resistance in most organic and inorganic acids, salt solutions, strong alkalis and a few molten salts. The passive oxide film (corrosion barrier) is stable in both reducing and oxidizing conditions. Zirconium is excellent in both acidic and basic solutions.
