Popis:	Single crystal AlN fibers [110] elongated up to 20 mm length and up to 40 μm diameter were obtained by self-propagating high-temperature synthesis (SHS) starting from a mixture of Al, AlN and NH4Cl under 100 atm. of N2. Two types of fibers were obtained: (i) long, thin fibers with smooth surfaces and diameter 20 μm) of “banderilla-type” having scores of crystalline ear-like projections aligned along generator lines on the fiber surfaces. The fibers grew by a vapor-solid mechanism in the axial geode-like region of the cylindrical AlN cake obtained after the SHS.
