Composition of aluminum nitride
WebAluminum and its alloys are characterized by their low hardness and less satisfactory tribological performance. These limits can be overcome by means of load-specific … WebAluminum carbide (Al 4 C 3), in the form of pale yellow crystals, can be made by heating a mixture of the elements at temperatures above 1000 °C. It reacts with water or dilute acids to form methane. Aluminum nitride (AlN) is synthesized by direct nitridation of aluminum at 800 °C. On hydrolysis by water it forms ammonia and aluminum hydroxide.
