Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Four in-house company studies (Saint-Gobain) on particle size distribution were conducted reporting D50-values of 3.347, 5.257, 22.042 and 107.387 µm. Additionally the D90 and D10 values were 9.224, 10.87, 49.977, 364.655 and 1.062, 1.307, 4.694 and 15.390 µm, respectively.

Additional information

It should be noted that zirconium dioxide has many particle size distributions depending on the manufacturing process and intended use as shown by the four studies performed. It is therefore not possible to conclude a representative D50 and all four values should be individually considered representative.
