A hexafluoride is a chemical compound with the general formula QX n F 6, QX n F 6 m−, or QX n F 6 m+. Many molecules fit this formula. Many molecules fit this formula. An important hexafluoride is hexafluorosilicic acid (H 2 SiF 6 ), which is a byproduct of the mining of phosphate rock .
The metals that make well-characterized hexafluorides include nine metals in the center of the periodic table (molybdenum, technetium, ruthenium, rhodium, tungsten, rhenium, osmium, iridium, and platinum) along with elements 92–94: uranium, neptunium, and plutonium. At room temperature, tungsten hexafluoride is a gas.
Many gases have toxic properties, which are often assessed using the LC 50 (median lethal concentration) measure. In the United States, many of these gases have been assigned an NFPA 704 health rating of 4 (may be fatal) or 3 (may cause serious or permanent injury), and/or exposure limits (TLV, TWA/PEL, STEL, or REL) determined by the ACGIH professional association.
