Name:
Named in 1872 by Félix Pisani in honor of Henri Étienne Sainte-Claire Deville [March 11, 1818 Saint Thomas, Virgin Islands - July 1, 1881 Boulogne, Hauts-de-Seine, Ile-de-France, France], French chemist. He was professor of chemistry at the University of Besançon from 1845 - 1851. In 1851-1859, he was professor of chemistry at École Normale Supérieure in Paris. He became professor of chemistry at the Sorbonne in 1859 - 1881. Deville discovered the first economical process to refine aluminum.
Devilline Group.

The calcium analogue of lautenthalite and campigliaite.
A dimorph (Unnamed (Dimorph of Devilline)) has been found in both a slag and a mine dump.

Visually very similar to orthoserpierite and bladed serpierite.
