Disclosed is a method for producing a molded fluoride crystal article which has a different shape from that of a fluoride crystal base and has excellent optical properties readily. The method comprises heating the fluoride crystal base at a temperature lower than the melting point of the fluoride crystal base while compressing to mold the fluoride crystal base into a predetermined shape. In the method, the fluoride crystal base is compressed to initiate the deformation of the fluoride crystal base through recrystallization and the deformation is allowed to proceed until the fluoride crystal base has the predetermined shape. |
