Abstract
Nano-structures of Aluminum Nitride and a method of producing nano-structures of Aluminum Nitride from nut shells comprising milling agricultural nuts into a fine nut powder, milling nanocrystalline AlOinto a powder, mixing, pressing the fine nut powder and the powder of nanocrystalline AlO, heating the pellet, maintaining the temperature of the pellet at about 1400° C., cooling the pellet, eliminating the residual carbon, and forming nano-structures of AlN. An Aluminum Nitride (AlN) product made from the steps of preparing powders of agricultural nuts using ball milling, preparing powders of nanocrystalline AlO, mixing the powders of agricultural nuts and the powders of nanocrystalline AlOforming a homogenous sample powder of agricultural nuts and AlO, pressurizing, pyrolyzing the disk, and reacting the disk and the nitrogen atmosphere and forming AlN.
