Fluor :: Fluor (n.) A fluid state.

Fluor :: Fluor (n.) Menstrual flux; catamenia; menses.

Fluor :: Fluor (n.) See Fluorite.

Fluor Albus :: Fluor albus () The whites; leucorrhaea.

Fluor Spar :: Fluor spar () See Fluorite.

Fluoranthene :: Fluoranthene (n.) A white crystalline hydrocarbon C/H/, of a complex structure, found as one ingrdient of the higher boiling portion of coal tar..

Fluorated :: Fluorated (a.) Combined with fluorine; subjected to the action of fluoride.

Fluorene :: Fluorene (n.) A colorless, crystalline hydrocarbon, C13H10 having a beautiful violet fluorescence; whence its name. It occurs in the higher boiling products of coal tar, and is obtained artificially..

Fluorescein :: Fluorescein (n.) A yellowish red, crystalline substance, C20H12O5, produced by heating together phthalic anhydride and resorcin; -- so called, from the very brilliant yellowish green fluorescence of its alkaline solutions. It has acid properties, and its salts of the alkalies are known to the trade under the name of uranin..

Fluorescence :: Fluorescence (n.) That property which some transparent bodies have of producing at their surface, or within their substance, light different in color from the mass of the material, as when green crystals of fluor spar afford blue reflections. It is due not to the difference in the color of a distinct surface layer, but to the power which the substance has of modifying the light incident upon it. The light emitted by fluorescent substances is in general of lower refrangibility than the incident l

Fluorescent :: Fluorescent (a.) Having the property of fluorescence.

Fluorescin :: Fluorescin (n.) A colorless, amorphous substance which is produced by the reduction of fluorescein, and from which the latter may be formed by oxidation..

Fluoric :: Fluoric (a.) Pertaining to, obtained from, or containing, fluorine..

Fluoride :: Fluoride (n.) A binary compound of fluorine with another element or radical.

Fluorine :: Fluorine (n.) A non-metallic, gaseous element, strongly acid or negative, or associated with chlorine, bromine, and iodine, in the halogen group of which it is the first member. It always occurs combined, is very active chemically, and possesses such an avidity for most elements, and silicon especially, that it can neither be prepared nor kept in glass vessels. If set free it immediately attacks the containing material, so that it was not isolated until 1886. It is a pungent, corrosive, colorles

Fluorite :: Fluorite (n.) Calcium fluoride, a mineral of many different colors, white, yellow, purple, green, red, etc., often very beautiful, crystallizing commonly in cubes with perfect octahedral cleavage; also massive. It is used as a flux. Some varieties are used for ornamental vessels. Also called fluor spar, or simply fluor..

Fluoroid :: Fluoroid (n.) A tetrahexahedron; -- so called because it is a common form of fluorite.

Fluoroscope :: Fluoroscope (n.) An instrument for observing or exhibiting fluorescence.

Fluorous :: Fluorous (a.) Pertaining to fluor.

Hydrofluoric :: Hydrofluoric (a.) Pertaining to, or containing, hydrogen and fluorine; fluohydric; as, hydrofluoric acid..

Silicofluoric :: Silicofluoric (a.) Containing, or composed of, silicon and fluorine; especially, denoting the compounds called silicofluorides..

Silicofluoride :: Silicofluoride (n.) A fluosilicate; a salt of silicofluoric acid.

Stannofluoride :: Stanno- () A combining form (also used adjectively) denoting relation to, or connection with, tin, or including tin as an ingredient..
