Acid Leaching of SHS Produced MgO/TiB2
… thermite reaction involving magnesium oxide (MgO), titanium dioxide (TiO₂), and boron oxide (B₂O₃) forms titanium diboride (TiB₂) and MgO as final products. Selective acid leaching is used to remove the MgO leaving high purity TiB₂ powder. The SHS method to produce TiB₂ is attractive because …

ELECTROLYTIC DEPOSITION OF MgO ON STAINLESS STEEL SUBSTRATE
The main objective of this thesis was to fabricate and characterize magnesium oxide coating on stainless steel alloy (SAE 316L). Electrolytic processing, followed by sintering was used for making it. Coating the heater tubes used in refinery industry with magnesium oxide is expected to increase the …

Optical reflectance spectra of chromium (III) in MgO-ss
… ion, chromium, was investigated in a MgO host lattice. The chromium ion incorporated into poly-crystalline MgO by quenching from elevated temperatures allowed investigation of a single crystalline phase, MgO-solid solution (ss). The chromium ion was confirmed to occur in the trivalent …

Spin dependent transport in continuous and discontinuous CoFeB/MgO heterostructures
… transport between CoFeB electrodes through an MgO barrier in ordered and disordered multilayer systems. The local electrical integrity of the MgO barrier was studied using Ru and CoFeB bottom electrodes by a modified conducting atomic force microscopy. The quality of the MgO barrier was …

Reactive MgO and Self-healing Microcapsules for Enhanced Well Cement Performance
… and CaO-based expansive additives, MgO has many advantages including a thermally stable hydration product, relatively low water requirements for hydration, and designable expansion properties. These make MgO a promising candidate for delivering the desired expansion under the complex …

Einfluss von Aluminiumoxid- und Titanoxid-Additiven auf die Thermoschockbeständigkeit von MgO-teilstabilisiertem Zirkonoxid
… i.e. alumina and titania are supplied to MgO partially stabilized zirconia (Mg-PSZ). The Mg-PSZ is partially destabilized during sintering and spinel is formed in situ. Both processes lead to local elongation, which generates internal stresses and finally a crack structure is formed that …

Experimental determination of the phase equilibrium in the Cu-O-ZnO-SiO2-CaO-MgO system
… the phase relationship in the Cu-O-ZnO-SiO2-CaO-MgO system and its subsystems. Phase relationships in a wide temperature range (1000 °C – 1700 °C), and at various oxygen partial pressures (pO2 = 0.21 atm, pO2 = 0.01 atm, and in pure argon) have been systematically studied. Liquidus compositions …

The Role of Reactive MgO as an Expansive Additive in the Shrinkage Reduction of Concrete
Hard-burnt magnesium oxide (MgO) has been successfully used in large volume concrete, mainly dam construction in China, for thermal shrinkage reduction since the 1970’s. At ~4% addition to the cement by weight, it is much simpler than conventional shrinkage measures and in particular, reduces the …

Growth and Characterisation studies of MgO and Mg silicate dielectric layers on Si and InP surfaces
… investigates the suitability of magnesium oxide (MgO) and magnesium silicate as possible high-k dielectric materials on both silicon and indium phosphide (InP) surfaces. Given that the emphasis of this study was controlling the semiconductor/high-k interface formation, the principle experimental …

Radiation-Enhanced Diffusion and Defect Production During Ion Irradiation of MgO and Al(2)O(3)
… Ca and Zn buried tracer layers in MBE grown MgO was measured following irradiation with either 2.0 MeV Kr or 1.0 MeV Ne, He or H from 30 to 1500$\sp\circ$C. This represents the first reported RED measurements on an oxide system. Ion beam mixing at 30$\sp\circ$C on both sublattices was …
