Zirconium's distinctive properties make it a popular choice for fusions and fluxes in analytical chemistry and chemical processing.

• Crucibles feature a snap-on ring
• Removable ring snap-fits into a machined groove approximately 0.20" below the top of the crucible

Fluxes that can be used in these zirconium crucibles include sodium peroxide fusion, sodium carbonate fusion, and lithium salt fusion. Prolonged exposure to air at temperatures of more than 750 °C can have a negative effect on zirconium.
