Zirconia crucibles are prized for their high-temperature stability and chemical inertness. Key applications and products include:
Metal Melting: Crucibles for precious metals (gold, silver, platinum) and reactive metals.
Chemical Analysis: Lab crucibles for sample prep, ashing, and high-temperature reactions.
Crystal Growth: Specialized crucibles for controlled crystal growth.
Glass Melting: Crucibles for high-quality optical glass production.
Pigment Production: Crucibles for high-temperature pigment synthesis.

Selecting the appropriate zirconia crucible depends on several factors:
