An X-ray diffraction study of the system Al2S3-In2S3 in the In-rich region
A series of samples in the system Al_2S_3-In_2S_3 in the In-rich region have been synthesized and studied by X-ray diffraction. At the lowest values of the Al/In (molar) ratio, r, the existing phase beta is isostructural with the room-temperature, ordered, tetragonal phase of In_2S_3. As the Al content increases a progressive disorder of cations takes place. For r>1/10 this disorder is completed and beta is replaced with a phasedenoted as alpha, which is isostructural with the first high-temperature, cubic, phase of In_2S_3. The unit-cell parameters of the ternary beta and alpha alloys, (Al_XIn_(1-x))_2S_3, decrease linearly as the Al content increases. From r>1/3 to r~2/3 hhere is a two-phase region, alpha+gamma_1. The hexagonal phase gamma_1 is isostructural with AlInS_3, appearing at r=1, and with the second high-temperature, gamma, modification of In_2Se_3. The phase gamma_1 also exists in the systems Ga_2Se_3-In_2Se_3 and Al_2Se_3-In_2Se_3 in the In- rich region for the (GA, AL)/In (molar) ratio grater than ~1.50.
