Aluminum

open access: yes, 2022
Aluminum is the most abundant metal in the earth's crust. It occurs naturally in its oxidized state in a variety of sedimentary rocks such as bauxite. Alumina (Al2O3) is itself a material with good mechanical, chemical and thermal qualities, used traditionally in the production of ceramics. Its isomorphic form, beta-alumina, became a promising material

The Potential of Acousto-Ultrasonic Techniques for Inspection of Baked Carbon Anodes

open access: yesMetals, 2016
High quality baked carbon anodes contribute to the optimal performance of aluminum reduction cells. However, the currently decreasing quality and increasing variability of anode raw materials (coke and pitch) make it challenging to manufacture the anodes

Preparation of Aluminum Nitride/Aluminum Composites by Nitridation of Aluminum

open access: yesJournal of the Ceramic Society of Japan, 1993
AlN/Al composites were prepared by the nitridation of Al-MgO (0-7.5wt%) powder compacts at 1100-1400°C. The dense composite layer grew outward from the bottom surface of the powder compact at 1250-1400°C. The conversion of Al to AlN and the thickness of the composite increased with increasing content of MgO, reaction temperature and time.
