Most of the powder deposited separately in two regions in the reactor. The powder deposited in teh range between the end of AlCl_3-feeding tube and the point 17 cm apart there from consisted of one phase AlN. The particle size and its distribution became fine and uniform at high reaction temperature or at high total flow rate of NH_3 and N_2. Fine powder with the median diameter of 0.16μm was synthesized at 1190℃ and particles were within a narrow range from 0.1 to 3.0 μm. In the range between 20 and 33 cm apart from the end of the AlCl_3-feeding tube, amorphous AlN deposited, which crystallized on heating at 1400℃. By-product, NH_4Cl which coexisted with amorphous AlN, was easily eliminated by heating at 500℃. The formation rate of crystalline AlN was 2.2g・h^<-1> and the total yield of crystalline and amorphous AlN was 79%.}, pages = {206--210}, title = {Al_2Cl_3とNH_3の気相反応によるAlN微粉末の合成}, volume = {96}, year = {1988} }
