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
