AI Technical Summary
Technical Problem
Conventional methods for producing metal fluorides generate large amounts of corrosive gases such as hydrogen fluoride during the heating process.
Method used
A method involving mechanochemical treatment of a fluorine-containing compound and a basic metal compound, followed by heat-treatment, to form metal fluorides while minimizing corrosive gas generation, using equipment that is not highly corrosion-resistant and can be industrialized with general-purpose machinery.
Benefits of technology
The method effectively suppresses the generation of corrosive gases and allows for the production of metal fluorides using less expensive and more readily available equipment, facilitating industrial-scale production.

Abstract
The purpose of the present disclosure is to provide: a method for producing a metal fluoride; and a composition, whereby it is possible to produce the metal fluoride while suppressing the generation of a corrosive gas. The present disclosure relates to a method for producing a metal fluoride, the method comprising: a step (1) for subjecting a fluorine-containing compound and a basic metal compound containing at least one selected from the group consisting of alkali metals and alkaline earth metals to a mechanochemical treatment to obtain a composition containing the fluorine-containing compound and the basic metal compound; and a step (2) for heat-treating the composition to obtain a metal fluoride containing at least one selected from the group consisting of alkali metals and alkaline earth metals.
