Popis: Bicrystals containing symmetrical tilt boundaries with either the or the direction as the rotation axis were vapor-grown at 1740°C using the reaction 2AlCl3(g)+3CO2(g) + 3H2(g)→.Al2O3(s) + 6HCl(g) + 3CO(g). Specimens as large as 3 by 5 by 20 mm were produced in 24 h. Chemical purity of the specimens is high, with
