System:IsometricColour:Dark brown
Lustre:GreasyHardness:5
Name:The name reflects its antimony (Greek = STIBI) content, and relationship to Pyrochlore.
A variety of Pyrochlore Supergroup

Černý et al. (1979) defined stibiobetafite as the Sb3+ analogue of betafite; however, the type sample has Nb + Ta > Ti apfu, and Ca is the dominant species of the dominant-valence group at the A site. The type sample is now to be classified as oxycalciopyrochlore.

It is not possible to calculate the formula of stibiobetafite studied by Tindle & Breaks (1998) owing to errors in the table of analytical data.
