Nitridation of Aluminum Surface.

Tow-Step Synthesis of Aluminum Oxynitride (AlON) via Carbothermal and Nitridation Route

The aim of this research was to study synthesize gamma aluminum oxynitride powder with cubic spinel structure. In order to carry out this process, carbothermal reduction and nitridation of α-alumina as starting powder was used. This process was carried out in two steps, that in the first step at 1550˚C, a portion of α-alumina was reacted with carbon and aluminum nitride (AlN) was formed, then i...

The nitridation of ZnO nanowires

ZnO nanowires (NWs) with diameters of 50 to 250 nm and lengths of several micrometres have been grown by reactive vapour transport via the reaction of Zn with oxygen on 1 nm Au/Si(001) at 550°C under an inert flow of Ar. These exhibited clear peaks in the X-ray diffraction corresponding to the hexagonal wurtzite crystal structure of ZnO and a photoluminescence spectrum with a peak at 3.3 eV cor...

SPECIAL ISSUE: EARLY CAREER SCHOLARS IN MATERIALS SCIENCE In situ synthesis of cold-rollable aluminum–aluminum nitride composites via arc plasma-induced accelerated volume nitridation

Our study proposes in situ synthesis of cold-rollable aluminum nitride (AlN) reinforced aluminum matrix composites with attractive thermal properties via arc plasma-induced accelerated volume nitridation (APAVN). Within three minutes of repeated APAVN using commercial nitrogen gas, volume fraction of AlN increased up to 40 vol%, which is the highest value ever reported by in situ nitridation of...

Nitridation of InP(1 0 0) surface studied by synchrotron radiation

The nitridation of InP(100) surfaces has been studied using synchrotron radiation photoemission. The samples were chemically cleaned and then ion bombarded, which cleaned the surface and also induced the formation of metallic indium droplets. The nitridation with a Glow Discharge Cell (GDS) produced indium nitride by reaction with these indium clusters. We used the In 4d and P 2p core levels to...
