Abstract: The non-agglomerated Bi2O3 whiskers with a monoclinic structure were hydrother-mally prepared by using Bi(OH)3 and KOH. The hydrothermal reaction takes place in the ranges of 120～220℃ from 0.5 to 10h. The influences of the starting materials, reaction temperature and time on the morphologies of Bi2O3 whiskers were examined. The length and aspect ratio (length to diameter) of hydrothermally prepared Bi2O3 whiskers are in the ranges of 4～70μm and 5～16, respectively.

Key words: hydrothermal synthesis, whisker, bismuth oxide, mineralizer
