| 中文摘要 | A phenomenon of the whiskers growth on the bulk rare earth (RE)-intermetallic compounds of NdSn(3), NdIn(3), and LaPb(3) is reported. The whiskers formed spontaneously on all of the RE-intermetallic compounds after exposed to room ambience (21-28 degrees C/20-56% RH, relative humidity) for several days. Among the samples, the propensity of whisker growth for NdSn(3) is the strongest, on which the tin whiskers were flourishing and covered all of the surfaces after exposed to room ambience for 22 days; while LaPb(3) is the secondary and NdIn(3) is the last one. Observed by SEM, the whiskers were exhibited as different morphology, size, and number density. The XRD analysis confirms the existence of RE(OH)(3) after whiskers formed, also, the weight gain curve of the samples exposed to room ambience supports that a spontaneous chemical reaction of the RE-intermetallic compounds with water in room ambience takes place. In discussion, it is proposed that the fresh metal atoms released by the chemical reaction could be causative to result in nucleation and spontaneous growth of the whiskers, while the anisotropy of crystal structure could be a reason to understand the difference of the whisker growth behaviors between Sn and Pb.
