摘要：

4ZnO.B2O3.H2O whiskers were prepared from 2ZnO.3B2O3.3.5H2O under hydrothermal process at 160 degrees C for 10 h. The synthesized product was characterized by XRD, SEM, TG-DSC and FT-IR. SEM results showed that the synthesized 4ZnO.B2O3.H2O whiskers' length was about 310 mu m and the diameter was 0.20.3 mu m. Further study on the whiskers' growth process and mechanism showed that the formation of the whiskers went through three stages and the morphology of 4ZnO.B2O3.H2O changed from irregular particles to rod-like structures and finally to whiskers. The variation of the morphology of the 4ZnO.B2O3.H2O whisker with the concentration of the starting material was investigated. (C) 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
