fluo-Chem. and Min.|ˈfluːəʊ|Abbreviation of fluor, used as combining form in many names of compounds containing fluorine, as ˌfluoˈborate, a salt of fluoboric acid. ˌfluoˈboric acid, a name originally applied to the gas terfluoride of boron (BF3), now applied to the compound (H2B2O4.6HF) obtained by saturating water with this. ˌfluoˈcerine, ˌfluo-ˈcerite, a native fluoride of cerium and the allied metals. ˌfluo-ˈhydric (fluo-hydric acid) =fluorhydric. Also in the names of other acids of which fluorine is a component along with some other element as ˌfluoˈchromic, -siˈlicic, -tanˈtalic, -tiˈtanic acid, and in the names of salts as ˌfluo-ˈcarbonate, -ˈphosphate, -ˈsilicate, -ˈtantalate, -ˈtitanate, -ˈzirconate.1812Sir H.
