About Fluorkyuygenite
Formula:
Ca12Al14O32[(H2O)4F2]
Colour:
Colourless
Lustre:
Vitreous
Hardness:
5 - 5½
Crystal System:
Isometric
Member of:
Name:
Named for being the fluorine analogue of chlorkyuygenite.
The F analogue of chlorkyuygenite and H2O analogue of fluormayenite.
Microporous tetrahedral framework structure, with water molecules occupying about 2/3 of the structural cages.
The mayenite supergroup species (in general, coded as C12A7, or C12A7e-) show unique electrochemichal properties, with some anions in their structure (e.g., oxygen anions) migrating thorough the structure. As such, the mayenites behave as metals even though they are very non-metal in terms of general chemistry. Transitions seen in their structure may be related to superconducting. The mayenites represent a group of chemicals known as "salts of an electron", also known as electrides (e.g., Weber et al., 2021).
