Sažetak
A series of samples in the system Al_2Se_3-In_2Se_3 in the In-rich region have been synthesized and studied by X-ray diffraction. In the interval of the Al/In (molar) ratio r from r>1/50 to r<1/20 the system has a two-phase region, alpha + gamma_1, where alpha is isostructural with the room-temperature modification of In_2Se_3, and gamma_1 is isostructural with the second high-temperature modification, gamma, of In_2Se_3. For r>1/20, ternary gamma_1 alloys (Al_xIn(1-x))_2Se_3 are present alone and their unit-cell parameters decrease continuously as the Al content increases. These results are analogous with those obtained for the system Ga_2Se_3-In_2Se_3 in the In-rich region. The samples have been studied by differential thermal analysis and electron-probe microanalysis.
