摘要

fluoride crystal base and has a different shape to easily manufacture the excellent optical properties of fluoride crystal formed body provides a possible production method . And pressed together along with a fluoride crystal base material is heated at a temperature lower than the melting point of the manufacturing method for molding into a predetermined shape , pressing the base material to initiate transformation fluoride crystal by recrystallization and , then molded to the desired shape by deforming .
