摘要: Abstract 1. Part I: Experimental study Optical and X-ray techniques are used to the growth morphology of α-Al2O3 filamentary crystals produced by a heterogenous vapor-phase reaction. The results surveying large population specimens reveal occurrence with high-index axes. distributions directions in basal non-basal planes show low-index peaks superposed upon continuum high index directions. Chromium-doping modifies distribution enhancing growth. Hexagonal hillocks on plane rhomboidal ones {11 2 0} prism serve as indicators crystallographic 2. II: Interpretation High-index is interpreted phenomenologically terms non-equilibrium resultant velocity. Implications observed discussed various mechanisms theories.
