Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

A density value of 1.73 g/cm³ at 20 °C is nominated as the key study (Budavari 1996) among the other secondary sources. This peer-reviewed chemical handbook is considered as a reliable source reference in which the original data sources are traceable.

The original references for the other sources (Krono 1992, Millennium 2007) were not available for review and no further information is available. The reliability of these results is not assignable.

According to the CRC Handbook of Chemistry and Physics (2007, Lide DR Ed, CRC Press) the relative density of the hydrolysis product of titanium tetrachloride, i.e.titanium dioxide is about 4 (anatase = 3.9, brookite = 4.17, rutile = 4.26).
