Fluoride is the negative ion of the elementfluorine. The symbol for the element fluorine is F. Fluoride often is written as F-, which stands for the anion of fluorine that has a -1 electrical charge. Any compound, whether it is organic or inorganic, that contains the fluoride ion is also...
aFluorspar is the main resource of fluoride in fluorine products and widely used in metallurgy, chemical engineering as an important nonmetal strategic resource. 萤石是氟化物主要资源在氟素产品和用途广泛在冶金学,化学工程方面作为一种重要非金属战略资源。[translate] ...
Compounds of the element have been used historically a flux agent, designed to make metal and slag more fluid during the smelting process. Fluorine is also a component in hydrofluoric acid, a compound used inetching, and the gas also has some medical uses. Dentists usesodiumfluoride to help t...
Is Fluoride Toxic to Plants Is Fluoride an Essential Nutrient for Plants? What is Fluoride? Fluorine is the elemental form and is usually found in its ionic form which is called fluoride. As fluoride it forms salts with things like calcium, magnesium and sodium. Combining it with sodium produc...

After considerable research, it was suggested that the relatively high content of natural fluorine in our water supply was responsible. I accepted this conclusion for a time. The people who had great quantities of sodium fluoride and sodium silico fluoride as by-products of the aluminum and fertil...
in combination with phenolic cpds. e.g. hydroxybenzophenones, are used to stabilise fluorine-contg. vinyl polymers such as (co)polymers of vinyfluoride, against thermo-oxidative degradation during processing. The claimed stabiliser compsns. are synergistic and also have stabilising effect against the...
What Is Fluorite? Fluorite is the mineral form of calcium fluoride. It belongs to the minerals of halides. It crystallizes in isometric cubic habi
Fluorite, also known as Fluorspar, is basically a mineral that is made up of the elements Calcium and Fluorine. The word “Fluorite” originates from the Latin root “fluo” which means “to flow”. It was used before as a flux to decrease the viscosity of slags from iron smelting. ...
