Crystallography of PolluciteHide

Crystal System:

Isometric

Class (H-M):

m3m(4/m32/m) - Hexoctahedral

Space Group:

Ia3d

Setting:

Ia3d

Cell Parameters:

a = 13.67 Å

Unit Cell V:

2,554.50 Å³ (Calculated from Unit Cell)

Morphology:

Almost always massive, rarely in trapezohedral or cubic crystals usually with both forms present, but either form may be dominant.

Comment:

A monoclinic variety (C2/c) has also been reported (Kamiya et al., 2008). Pollucite may probably be (as is analcime) cubic, tetragonal, orthorhombic, monoclinic or triclinic, depending on ordering.
