Abstract: Ultrafine AlN powder, whose diameter was betweeen 5 and 80nm and purity was 98.4wt%, was synthesized by microwave heating in an atmosphere of nitrogen. Phenolformaldehyde resin and colloidal Al(OH)3 were used as starting materials. The properties of the powder were determined by means of XRD, TEM, and so on. The mechanism for microwave synthesis of ultrafine AlNpowder was discussed.

Key words: AlN, ultrafine powder, microwave synthesis
