System:MonoclinicColour:White
Lustre:PearlyHardness:3½
Name:Named in honor of Rauf Baratovich Baratov (1921{ ), Soviet petrologist, Institute of Geology, Dushanbe, Tajikistan.


Note: Some mineralogists consider baratovite to be OH-dominant, which would make katayamalite the same species, with the name baratovite having priority.

The Ti analogue of Aleksandrovite.
