Tin whiskers grew rapidly and spontaneously on NdSn(3) powder under atmospheric conditions. By in situ optical microscopy observation, the incubation period of whisker growth was found to be very short, only about 10 min to 30 min, and the whisker growth rate was very high (up to 73 angstrom/s). It is proposed that the strong tendency for whisker growth on NdSn(3) powder indicates that such growth is closely related to decomposition of NdSn(3) under atmospheric conditions. An electron beam irradiation effect on whisker growth was also observed, in which the whiskers cease to grow after observation by scanning electron microscopy (SEM).
