The densities of the two samples are summarised here:

Sample Density (g/cm3) 
3.23% w/w MgO  5.730
4.53% w/w MgO  5.740
Conclusions:
An average value of 5.735 g/cm³ was obtained for the density of magnesium zirconium oxide following an in-house company study using the He pycnometer method. The density of two different samples was measured, with a MgO content of 3.23 and 4.53% w/w.

Description of key information

An average value of 5.735 g/cm³ was obtained for the density of magnesium zirconium oxide based on the results of an in-house company study using the He pycnometer method. This study (Börger, 2016), reporting two density values for two test samples with different MgO content (3.23 and 4.53 % w/w), was considered as the key study.

Key value for chemical safety assessment
