    摘要:

    采用高比容鉭粉(< 0.45 μm)通過真空燒結(jié)的方法制備了多孔鉭金屬，研究了在1150 ℃條件下燒結(jié)保溫的時(shí)間（10，20，30，40, 50 min）對(duì)多孔鉭金屬的微觀結(jié)構(gòu)以及孔隙性質(zhì)的影響。實(shí)驗(yàn)發(fā)現(xiàn)多孔鉭金屬的孔隙率在50%(體積分?jǐn)?shù))附近，其積累體積大小分布為0.08 cm3/g

    Abstract:

    Porous tantalum materials were prepared by a vacuum sintering technique using fine tantalum powder (< 0.45 μm) as the starting raw material. Effects of sintering time (10, 20, 30, 40 and 50 min) at 1250 oC on the microstructures and the porous characteristics of the porous tantalum were investigated. The results show that the porous tantalum materials have the porosity of about 50% with pore size distribution of 0.08 cm3/g
