Crystallography of CorrensiteHide

Crystal System:
Orthorhombic
Cell Parameters:
a = 5.337 Å, b = 9.215 Å, c = 29.0 Å
Ratio:
a:b:c = 0.579 : 1 : 3.147
Unit Cell V:
1,426.23 ų (Calculated from Unit Cell)
Morphology:
Fine-grained, occasionally as barely visible flakes.
Comment:
Various unit cells have been proposed including hexagonal, also monoclinic

4.62 Å(30)
3.53 Å(60)
2.57 Å(30)
Comments:
LLC d-values (31-794). Basal d-values vary with type of corrensite. LLC usually is 28-29 Angstroms, but HLC ranges up to 32 Angstroms. LLC and HLC corrensite may be present in mixtures, but samples may contain only one type. LLC corrensite is uncommon compared to HLC corrensite. Intercalation with glycerol or ethylene glycol increases HLC basal spacing to 32 Angstroms, while LLC corrensite does not expand.
