Morphology

As coatings consisting of subhedral crystals; hexagonal platelets (up to ∼30 μm); Individual crystals: Tabular to lamellar habit and forming disordered aggregates.

Type-locality form

As sparse coatings concisting of subhedral crystals not larger than 10 μm as well as larger hexagonal platelets up to ∼30 μm

Comment

Note on the space group. The authors assumed the space group given by Krivovichev and Burns (2000) is correct and that the space group P31c given by Belokoneva et al. (2002) is incorrect, because "(...) application of the Addsym tool from the Platon program (Spek, 2009) indicates that the P31c structure has missing symmetries, which does not occur in the case of the P63mc structure." Belokoneva et al. (2002) give the unit-cell parameters a = 5.268(4) and c = 13.48(1) Å.
