Chem. and Min. Abbreviation of FLUOR, used as combining form in many names of compounds containing fluorine, as Fluoborate, a salt of fluoboric acid. Fluoboric acid, a name originally applied to the gas terfluoride of boron (BF3), now applied to the compound (H2B2O4. 6 HF) obtained by saturating water with this. Fluocerine, Fluocerite, a native fluoride of cerium and the allied metals. Fluohydric (acid) = Fluorhydric. Also in the names of other acids of which fluorine is a component along with some other element as Fluochromic, -silicic, -tantalic, -titanic acid, and in the names of salts as Fluo-carbonate, -phosphate, -silicate, -tantalate, -titanate, -zirconate.
