Used as an intermediate for the production of other zirconium compounds

Zirconium Basic Carbonate (ZBC) is a moist, white, inhomogeneous, amorphous cake containing approximately 40% ZrO₂.  It is soluble in both mineral and organic acids as well as alkaline carbonates. It is insoluble in water. 
The material must be handled and transported with care to avoid dewatering and deactivation. It is recommended that ZBC is used within 6 months from production date.

CAS Number:             57219-64-4
Chemical formula:    Zr₂(CO₃)(OH)₂O₂
Appearance:              White paste
Packaging:                 25kg bags, 1000kg bulk bags

Typical Chemical Analysis:

ZrO₂ + HfO₂*            40% min.
Fe₂O₃                         0.002% max.
TiO₂                            0.002% max.
Na₂O                          0.05% max.
Cl                                0.05% max.
SO₄                             0.05% max. 

HfO₂ accounts for approximately 2wt% of this total.
