Anhidridit

Anhidridit is a term that has appeared in informal, educational, and occasionally fictional contexts to denote a dehydrated mineral or anhydride-derived compound. It is not an officially recognized mineral species or chemical substance in major reference works on geology or chemistry.

The name appears to be shaped by the mineral-naming convention using the suffix -it and by the word anhydride or anhydride-derived dehydration. This etymology mirrors real minerals such as anhydrite, although anhidridit is not established as a unit in those families.

Because there is no formal definition, usage varies. In some descriptions, anhidridit is described as a hypothetical dehydration product of a hydrated mineral or of anhydrides; in others, it is used as a placeholder label in classroom demonstrations of dehydration concepts.

Consequently, reliable identification, composition, and properties are not defined. Readers are advised to treat mentions of anhidridit as non-official or fictional unless explicitly tied to a recognized nomenclature or source.
