Mechanochemical synthesis and electrical conductivity of nanocrystalline delta-Bi2O3 stabilized by HfO2 and ZrO2

A powder mixture of a-Bi2O3 and HfO2, in the molar ratio 2:3, was mechanochemically treated in a planetary ball mill under air, using zirconium oxide vials and balls as the milling medium. After 50 h of milling, the mechanochemical reaction led to the formation of a nanocrystalline a-Bi2O3 phase (fl...
