Anhydrite

Definition - What does Anhydrite mean?

An anhydrite is an evaporite group of minerals with a whitish or off-white color that is formed by the precipitation of calcium sulfate when water is removed from salt and sulfate deposits.

Corrosionpedia explains Anhydrite

Erosion corrosion may occur when calcium sulfate is used in fluidized beds as combustion material from the reaction of limestone and sulfur with a coal fuel according to corrosion lab tests that are typically performed with pure chemicals and moisture saturated air. Metals that are annealed with normal microstructures and clean surfaces are typically used for testing purposes.
