Abstract

Self-consistent band structure and density of state calculations were performed for the pure Alumina (corundum phase) and the aluminates α–Al2-xTxO3 where T is a transition metal and stands for Sc, Y, La and Ac with x = 0...

Aluminizing is one of the processes that increases the resistance to corrosion and oxidation of the steels at high temperatures. During this process, the intermetallic compounds that formed on the steel surface, causes desirable properties. Among...

In this study, aluminizing of carbon steel with different microstructures was investigated by hot dipping into molten pure aluminum. For this purpose, low carbon and medium carbon steel samples were annealed, normalized and quenched to achieve...

In this study, alumina and calcium aluminate were prepared through microwave combustion method (MCM) and then were modified by potassium hydroxide as solid base catalysts. The catalytic activities were evaluated in the transesterification reaction...

Abstract

The optical properties of high k-gate α-Al2O3 and the effect of doping La have been studied by first principles using the density functional theory. The calculations were performed using the full ...
