Zirconium Crucibles

Zirconium Crucibles

Zirconium crucibles are made from high purity Zirconium. Zirconium is a reactive metal which is corrosion resistant due to the formation of a chemically inert oxide film. Zirconium crucibles can replace Platinum crucibles in many cases. The lids for the Zirconium crucibles are optional and have to be purchased separately. Features are:

  • Can be used up to 450°C (842°F)
  • Effective crucible for fusions using sodium carbonate or sodium peroxide
  • Can replace Platinum in many cases
  • Cost effective for high throughput compared to steel and porcelain
  • Resistant to mixtures of alkaline, carbonate hydroxide, peroxide borate, nitrates and some fluorites
  • Resistant to nitric acid and sulfuric acid below 75%
  • Not resistant to HF
