Message: | Ionic compound, dissolving to give separated Na+ and F− ions. Like sodium chloride, it crystallizes in a cubic motif where both Na+ and F− occupy octahedral coordination sites; its lattice spacing, approximately 462 pm, is somewhat smaller than that of sodium chloride.The mineral form of NaF, villiaumite, is moderately rare. It is known from plutonic nepheline syenite rocks.Applications:-Fluoride supplementation has been extensively studied for the treatment of postmenopausal osteoporosis-Fluoride salts are often added to municipal drinking water (as well as certain food products in some countries) for the purposes of maintaining dental health. The fluoride enhances the strength of teeth by the formation of fluorapatite, a naturally occurring component of tooth enamel-A variety of specialty chemical applications exist in synthesis and extractive metallurgy. It reacts with electrophilic chlorides including acyl chlorides, sulfur chlorides, and phosphorus chloride. Like other fluorides, sodium fluoride finds use in desilylation in organic synthesis.-Sodium fluoride is used as a cleaning agent (e.g., as a "laundry sour") url:http://www.beryliumfluoride.com |
