About Phosphohedyphane
Formula:
Ca2Pb3(PO4)3Cl
Colour:
Colourless
Lustre:
Vitreous, Greasy
Hardness:
4
Specific Gravity:
5.92 (Calculated)
Crystal System:
Hexagonal
Member of:
Name:
For its phosphate content and relationship with hedyphane.
Type Locality:
Isostructural with:
The phosphate analogue of hedyphane. The Pb3Ca2 analogue of pyromorphite and chlorapatite. The Cl analogue of fluorphosphohedyphane.
An unnamed OH analogue is IMA-coded as UM2002-53-PO:CaHPb.
Pb and Ca atoms are ordered on two different sites in the crystal structure.
Specimens from numerous localities worldwide have previously been labelled "calcian pyromorphite", and some of them may be identical with this species.
