Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Version / remarks:
The above information referes to the information from the manufacturer of the Jolting Volumeter STAV II (J. Engelsmann AG, Germany).
Principles of method if other than guideline:
The tapped density is an increased bulk density of the powder after a specified compaction process. The tapped density is obtained by mechanically tapping a graduated measuring cylinder containing the powder sample. After observing the initial powder volume and mass, the cylinder is mechanically tapped. The tapped density of the silica powder was measured by placing a defined amount of the powder into a 100ml graduated cylinder, which was tapped 500 times using Jolting Volumeter STAV II (J. Engelsmann AG, Germany). The volume occupied by the powder was then read and the density calculated based on the mass to volume ratio.

Tap density for synthetic amorphous calcium magnesium silicate was determined to 0.1 -0.25 g/ml at 20.0 -25.0 degree celcius.

Conclusions:
Tap density for synthetic amorphous calcium magnesium silicate (CMS) was determined to 0.1 -0.25 g/ml.
