Abstract:
The paper displays results of the study, which show that changes of corundum morphology are directly linked with various ranges of minor Cr and Fe contents. Cr3+ ions, being larger than Al3+ ions, entering in the crystal structure make it elongated along the axis с. The mutual entering of Cr3+ and Al3+ ions leads to the accelerated growth of the dipyramidal faces. The larger content of minor Fe, as related the Cr one (3 : 1 and more) put forward to the quicker growth of rhombohedron and the c pinacoid faces.
