FIELD: inorganic syntheses. SUBSTANCE: heated aluminum is treated by gaseous aluminum halides with velocity 0.1-6.9 cu.cm/min per 1 sq.cm of condensation surface and simultaneously by nitrogen-containing gases, aluminum to nitrogen ratio being maintained at the level 1:(1.2-12) and condensation being conducted on substrate of compact polycrystalline aluminum nitride. EFFECT: provided manufacturing aluminum nitride fibers with length to diameter ratio higher than 100.
