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
• 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
