摘要：
A method of making Aluminum Nitride (AlN) from nut shells comprising preparing powders of agricultural nuts, preparing powders of nanocrystalline Al2O3, mixing the powders and thereby forming a homogenous sample powder of agricultural nuts and Al2O3, pressurizing the homogenous sample powder into a disk, heat treating or pyrolyzing the disk in a nitrogen atmosphere, reacting the disk and the nitrogen atmosphere and forming AlN, and wherein the AlN is nano-structured AlN and in a pure form and in the wurtzite phase of AlN. A method of producing Aluminum Nitride comprising milling nuts into a powder, milling a powder of nanocrystalline Al2O3, mixing, pressing into a pellet, providing nitrogen, heating, and forming AlN. An Aluminum Nitride product from preparing powders of nuts and Al2O3, mixing, and forming a powder, pressurizing into a disk, pyrolyzing in nitrogen, and forming AlN.
