• Be-based materials
• Be-Cu capsule
• Be2C ablator
• high purity

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, Be2C 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. Be2C coatings were first prepared by the DC reactive magnetron sputtering with a high deposition rate. (similar to 300 nm/h). Pure polycrystalline Be2C films with uniform microstructures, smooth surface, high density. (similar to 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.
