Description of key information

The tap density of [µ-[carbonato(2-)-O:O']]dihydroxydioxodizirconium was determined to be 0.651 g/cm3 at ambient conditions (Bradshaw , 2010).

Key value for chemical safety assessment

Additional information

The tap density was determined as due to the physical and chemical nature of this substance, other methods for determining the density are not applicable, e.g. pycnometry cannot be used as the material changes due to loss of moisture on degassing.
