fluoceriten.

Brit. /ˌfluːəˈsɪərʌɪt/, U.S. /ˌfluəˈsɪˌraɪt/
Origin: A borrowing from German. Etymon: German Fluocerit.
Etymology: < German Fluocerit (in neutraler Fluocerit : C. F. A. Hartmann Lehrbuch der Mineral. u. Geol. (1835) I. 227; see below, and compare †Flußcerit , †Ceriumfluat (both 1831 or earlier)) < fluo- fluo- comb. form + cer- (in Cerium cerium n.) + -it -ite suffix1, after French flucérine fluocerine n. Compare French fluocérite (1859 or earlier), Compare later fluocerine n., and also earlier cerite n.1Hartmann used German Fluocerit to denote both fluocerine and fluocerite, distinguishing them by the qualifying adjectives basisch and neutral. The earliest German mineralogist who used Fluocerit on its own to denote fluocerite appears to have been W. Haidinger ( Handbuch der bestimmenden Mineral. (1845) 500).
