| Abstract: | The temperature dependence of the dynamic
viscosity of In-Sb alloy melts has been investigated using
a torsional oscillation viscometer. The results show that no anomalous change
in viscosity occurs in In-1 wt.%Sb melt and an anomalous change occurs at about
800oC both in In-55 wt.%Sb and In-69.5 wt.%Sb alloy melts. A low
temperature area (LTA) and a high temperature area (HTA) can be used to
describe the viscosity behaviour of In-55 wt.%Sb and In-69.5 wt.%Sb alloy
melts. The activation energy of In-Sb alloy melts has been obtained. Variation
of activation energy with temperature of In-Sb melts has been observed. The
structural variation of In-Sb alloy melts has also been discussed on the basis
of the change in viscosity and DSC analysis. |
