Sažetak
Structural properties of the system (1-x)Al2O3+xCr2O3 were investigated in the whole concentration range. The samples were prepared by mechano-chemical activation of γ-AlOOH and Cr2O3, sintering the resulting powder up to 1300°C. The formation of solid solutions (Al1-xCrx)2O3 was observed in the whole concentration range. The replacement of Al3+ with Cr3+ resulted in a gradual increase of the unit-cell parameter with x. For the molar fraction of Cr2O3, x≥0.5, a phase closely related to Cr2O3 was also found. The unit-cell parameters of this phase also increased with x, although the rate of increase was much smaller. The samples of (1-x))Al2O3+xCr2O3 showed gradual changes in the FT IR spectra with x.
