Production method of Cu In Ga alloy powder, production method of Cu In Ga Se alloy powder and production method of Cu In Ga Se alloy sintered body, Cu In Ga alloy powder and Cu In Ga Se alloy powder

摘要

Production method of the Cu In Ga alloy powder of this invention produces the Cu In Ga alloy hot water, solidifies the particular hot water with strip cast method and the production Cu In Ga alloy draws up the band thin, the particular alloy pulverizes the band thin. According to this production method, it is possible to produce the Cu In Ga alloy powder which possesses with the 2nd territory of the granularity which designates the 1st territory and the Cu Ga alloy which designate In as the main component as the main component and disperses in the 1st territory. Here, mixing this Cu In Ga alloy powder with the Se powder, when it makes alloy, the exoergic reaction of Se and In which occur in the 1st territory, being abated by the endoergic reaction of Se and Cu which occur in the 2nd territory, scattering the hot water with the explosive reaction is prevented, it becomes possible to produce the Cu In Ga Sn alloy powder safely.
