Conclusions:
Calcium titanate has a pour and tap density of 0.43 g/mL and 0.58 g/mL, respectively.
Executive summary:

An experiment was undertaken in line with CIPAC MT 186 (Bulk Density) to obtain the bulk density of calcium titanate. The pour and tap (solids) technique was followed so as to determine the pour and tap density. In conclusion, calcium titanate was found to have a pour density of 0.43 g/mL and tap density of 0.58 g/mL.

Conclusions:
The bulk density of calcium titanium trioxide was found to be 4.19 ± 0.02 g/cm3.
Executive summary:

To ascertain the bulk density of calcium titanium trioxide, an experiment was undertaken using the gas pycnometry technique in line with OECD Guideline 109 (Density of Liquids and Solids). No deviation in the procedure was specified. The average result for the bulk density of calcium titanium trioxide was concluded to be 4.19 ± 0.02 g/cm3.

Description of key information

A pour density of 0.43 g/mL and tap density of 0.58 g/mL was calculated for the bulk density of calcium titanate. The bulk density of calcium titanium trioxide was determined to be 4.19 ± 0.02 g/cm3.
