Abstract

The thermal behaviour of bimetallic films was studied by the thermogravimetric analysis between 25 and 550°C at 10°C min−1. The kinetic parameters derived from non-isothermal thermogravimetric data are presented. The synthesis of several bimetallic films of InSn, InGa and InCd with solvents such as acetone, 2-butanone and 2-propanol is described. The differences in thermal stability are compared with those of indium films prepared with the same solvents. The activation energies of these alloys are less than that of the pure metal. The decomposition reactions were found to be 0.5 and 1.0 order. The decomposition temperatures and pre-exponential factors were determined.
