Effects of ball milling on pure antimony, on GaSb alloy and on Ga+Sb powder mixture; oxidation, glass formation and crystallization

Elemental polycrystalline antimony powder, a mixture of antimony and gallium powder, and a Ga-88at.%Sb alloy were mechanically alloyed or ground by high-energy ball milling in an air atmosphere. An excessive oxidation of antimony was observed and this gave us the possibility to estimate the temperat...

Description
Summary:Elemental polycrystalline antimony powder, a mixture of antimony and gallium powder, and a Ga-88at.%Sb alloy were mechanically alloyed or ground by high-energy ball milling in an air atmosphere. An excessive oxidation of antimony was observed and this gave us the possibility to estimate the temperature of the milling process in our case. The mechanical grinding of the Ga-88at.%Sb alloy first produced an amorphous oxide, which subsequently crystallized on further milling.
