Abstract
A method of manufacturing phosphorus pentafluoride and hexafluorophosphate can suppress the manufacturing cost and also can manufacture high-quality phosphorus pentafluoride from an inexpensive and low-quality raw material. The raw material for the method can include at least a phosphorus atom and a fluorine atom. These are brought into contact with a carrier gas, and a phosphorus pentafluoride is extracted and separated into the carrier gas. A method of manufacturing hexafluorophosphate includes reacting fluoride with the resulting phosphorus pentafluoride according to the following chemical reaction scheme: sPF+AF→A(PF), in which s is in the range of 1≦s≦3, and A is at least one of the following: Li, Na, K, Rb, Cs, NH, Ag, Mg, Ca, Ba, Zn, Cu, Pb, Al and Fe.
