AlN whiskers grown by combustion of Al powder under high nitrogen pressure
were investigated. Several types of whiskers' structures, such as wavy stru
cture, crossed structure, stack structure, bead-necklace structure, branch
structure, dendritic crystal, were found due to the variation of growth con
ditions. The causes of some structures were explained. (C) 2000 Kluwer Acad
