摘要：
A manufacturing method for a neutron moderating material is provided, and includes: providing a metal fluoride powder, a lithium fluoride powder and an aluminum metal powder； applying a first wet mixing step to add the aluminum metal powder and the lithium fluoride powder into an organic solvent to form an aluminum-lithium fluoride slurry； applying a second wet mixing step to add the metal fluoride powder into the aluminum-lithium fluoride slurry to form a metal fluoride-aluminum-lithium fluoride slurry； drying the metal fluoride-aluminum-lithium fluoride slurry to form a metal fluoride-aluminum-lithium fluoride composite powder； and forming and densifying the metal fluoride-aluminum-lithium fluoride composite powder by a hot press process to form a fluoride-aluminum composite material. The fluoride-aluminum composite material has a relatively fine and uniform structure, a high relative density, a high purity, and a high bending strength, and thus can be used in a boron neutron capture therapy device.一種中子減速材料之製作方法，包括：提供金屬氟化物粉體、氟化鋰粉體及鋁金屬粉體；將鋁金屬粉體與氟化鋰粉體於一有機溶劑中進行一第一濕式混粉步驟，以形成鋁-氟化鋰漿體；加入金屬氟化物粉體於鋁-氟化鋰漿體中進行一第二濕式混粉步驟，以形成金屬氟化物-鋁-氟化鋰漿體；乾燥該金屬氟化物-鋁-氟化鋰漿體，以形成金屬氟化物-鋁-氟化鋰複合粉體；及以熱壓製程成型及緻密化該金屬氟化物-鋁-氟化鋰複合粉體，以形成氟化物-鋁複合材料，其組織細緻、均勻，相對密度高，純度高，彎曲強度大，可應用於硼中子捕獲治療設備當中。
