General Hydrophilite Information

Chemical Formula:

CaCl2

Composition:

Molecular Weight = 110.98 gm

Calcium 36.11 % Ca 50.53 % CaO

Chlorine 63.89 % Cl 63.89 % Cl

- % Cl -14.42 % -O=Cl₂

______ ______

100.00 % 100.00 % = TOTAL OXIDE

Empirical Formula:

CaCl₂

Environment:

Found with anhydrite, gypsum and halite. Hydrophillite (1813) was inadequately characterized and is probably antarcticite or sinjarite.

IMA Status:

Discredited IMA 2006

Locality:

Luneberg, Hannover, Germany Link to MinDat.org Location Data.

Name Origin:

From the Greek hydros = "water" and philos = 'friend' in allusion to the highly deliquescent nature of the mineral.

Synonym:
