Phase transformations at reduction of corundum

Dan`ko, A.Ya.; Rom, M.A.; Sidelnikova, N.S.; Kaltaev, Kh.Sh.; Nizhankovsky, S.V.; Fedorov, A.I. (Functional Materials, 2007)

Research results are presented on the corundum structure transformation caused by reducing annealing. The annealing at 1500-2000°C in Ar atmosphere at CO + H₂ concentration 0.1-10 vol.% and N₂ 0.1-0.4 vol.% has been found ...
Structure perfection of bulk and near-surface layers in sapphire single crystals

Tkachenko, V.F.; Puzikov, V.M.; Dan`ko, A.Ya.; Budnikov, A.T.; Lukienko, O.A. (Functional Materials, 2007)

Triple-crystal X-ray diffractometry has been used to study the structure perfection in bulk and surface layer of basal-oriented sapphire single crystals grown using horizontal directional crystallization (HDC) in reducing ...
Study of nature of some defects visible in polarized light in sapphire signle crystals

Tkachenko, V.F.; Dan`ko, A.Ya.; Puzikov, V.M.; Budnikov, A.T.; Lukienko, O.A.; Sidelnikova, N.S.; Adonkin, G.T. (Functional Materials, 2007)

Using the precision technique of triple-crystal X-ray diffractometry, the structure of defect parts has been studied in large-size sapphire crystals grown by the horizontal directed crystallization in reducing gas media. ...
