Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If incompletely calcined zircon flour
Partial dissociation products remain zircon classification.
If thorium-contaminated nuclear grade
Thorium-bearing zirconias classify as complex acids per notes.
If significant sodium zirconate byproduct
Sodium salts of zirconic acid have separate classification.

Import Tips & Compliance
• XRF confirming >99% ZrO2 post-plasma treatment differentiates from zircon
• Calcination temperature records (2200°C+) prove complete ZrSiO4 dissociation
• Free silica content <0.1% analysis prevents mineral classification
