碩士 === 國立成功大學 === 化學工程學系碩博士班 === 90 === A new combustion synthesis process was developed for the production of AlN powder. Sheet aluminum powders mixing with or without NH4Cl or AlN were poured into a porous container made by aluminum foil with one open end or coating a layer of AlN inside the aluminum foil before pouring the reactant. The container was then placed in a stainless reactor filled with nitrogen pressure around 1~3 atm. A combustion synthesis reaction was ignited by heating the top surface and the heating power was about 900~1000W. Then, the reactant converted to AlN. In this experiment, several experimental parameters affecting the combustion synthesis reaction and product yield were investigated, e.g. the effect of coating a layer of AlN inside the aluminum foil, the addition content of NH4Cl, AlN and mixture of above two component. We have some conclusions of the above experimental parameters.
