| titleOfInvention | Recycling method of raw materials for metal fluoride single crystals |
| abstract | In a method for producing a metal fluoride single crystal by the Czochralski method, there is provided a method for recycling a raw material metal fluoride remaining in a crucible without being converted to a single crystal after completion of pulling of the single crystal. The recovered raw material metal fluoride is purified preferably using a gas scavenger made of a fluorine-based gas such as carbon tetrafluoride. The purification is particularly preferably carried out by melting the raw material metal fluoride in the presence of the fluorine-based gas, then evacuating it once, and then repeating the introduction of the fluorine-based gas and evacuation again.
