    摘要:

    研究了以鈀粉和碳酸鈉為原料制備多孔鈀的燒結(jié)-溶解新工藝，用FESEM分析了多孔鈀的微觀結(jié)構(gòu)形貌，并進(jìn)一步研究了制備的多孔鈀的力學(xué)性能和氫同位素的交排換代性能。結(jié)果表明，燒結(jié)-溶解工藝能穩(wěn)定地制備出孔隙率為85．29％-87．82％的多孔鈀，其壓縮強(qiáng)度大于2MPa。室溫下孔隙率為87.30％的多孔鈀對氘的單位質(zhì)量吸收量為0．0767L／g，氫同位素排代交換率為86．2％。

    Abstract:

    Porous Palladium materials have great importance in the storage, recycle and application of hydrogen isotopes. In this paper, porous Pd materials processed by a newly applied sintering-resolving technology are studied. The microstructures of the porous Pd materials are characterized by FESEM. In addition, their hydrogen isotopes displacement and mechanic properties arc studied. The results show that porous Pd materials with a porosity range from 85.29% to 87.82% can be stably processed by sintering-resolving technology. The compressive strength of the porous Pd materials exceeds 2 MPa. The deuterium absorption amount of the porous Pd material with a porosity of 87.3% is 0.0767 L/g and its hydrogen isotopes displacement ratio is 86.2% at room temperature.
