Kind Code:
A1
Abstract:
Disclosed is a process for producing a Cu-In-Ga alloy powder, the process comprising producing a melt of a Cu-In-Ga alloy, solidifying the melt by a strip casting method to produce a Cu-In-Ga alloy ribbon, and pulverizing the alloy ribbon. With this process, it is possible to produce a powder of a Cu-In-Ga alloy comprising a first region which comprises In as a main component and a second region which is granular, comprises a Cu-Ga alloy as a main component, and has been dispersed in the first region. When the Cu-In-Ga alloy powder is mixed and alloyed with a Se powder, the influence of the exothermic reaction of Se and In which takes place in the first region is lessened by the endothermic reaction of Se and Cu which takes place in the second region. Thus, melt scattering caused by an explosive reaction is prevented, and it becomes possible to safely produce a Cu-In-Ga-Sn alloy powder.
