Synthesis of an AIN Polycrystalline Bulk Layer and Nanotubes by Using NH^sub 3^ and Bi

A bulk layer of aluminum nitride (AIN) polycrystals was synthesized on a boron nitride crucible surface by heating Al chunks with 5 mol% of bismuth at 1273 K for 3 h under ... gas flow. The fragments of the layer were characterized by X-ray diffraction, scanning electron microscopy, and transmission...

Summary:A bulk layer of aluminum nitride (AIN) polycrystals was synthesized on a boron nitride crucible surface by heating Al chunks with 5 mol% of bismuth at 1273 K for 3 h under ... gas flow. The fragments of the layer were characterized by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The platelet grains of AIN with a size of 0.1-1.0 ...m and having preferred orientation of the c-axis perpendicular to the layer were formed at the crucible side. Nanotubes 6-15 ...m long and about 20-1 00 nm thick grew on the gas phase side of the layer. (ProQuest: ... denotes formulae/symbols omitted.)
