The Be-based materials with many particular properties lead to an important research subject. The investigation progresses in the fabrication technologies are introduced here, including main three kinds of Be-based materials, such as Be–Cu capsule, Be_2C ablator and high-purity Be material. Compared with the pioneer workgroup on Be-based materials,the differences in Be–Cu target fabrication were described, and a grain refinement technique by an active hydrogen reaction for Be coating was proposed uniquely. Be_2C coatings were first prepared by the DC reactive magnetron sputtering with a high deposition rate(~300 nm/h). Pure polycrystalline Be_2C films with uniform microstructures,smooth surface, high density(~2.2 g · cm~3) and good optical transparency were fabricated. In addition, the high-purity Be materials with metal impurities in a ppm magnitude were fabricated by the pyrolysis of organometallic Be.
