Abstract
A method for manufacturing aluminum nitride powder includes steps of: preparing a polymer powder, a wood powder having grain size similar with that of the polymer powder, and an alumina powder; and mixing the polymer powder, the wood powder and the alumina powder uniformly and forming granules to be carried out a single-replacement reaction by exposing the granules in a nitrogen-containing atmosphere at a temperature of 1680-1850° C.
