Bi4Ti3O12 is a tri-layer Aurivillius member compound that was reported to have good photocatalytic properties. Metal element doping and morphological particle tuning are strategies increase photocatalyst activity. In this research, the micro sheets Bi4Ti2.95V0.05O12 were synthesized using molten NaCl/KCl salt. The diffractogram shows sample successfully synthesized, however, there still found i...

Deoxidation of Ti, or direct removal of O dissolved in metallic Ti, is known to be extremely difficult when Mg is used as the deoxidizing agent. This difficulty arises because the chemical potential of O2, pO2, under Mg/MgO equilibrium is high (approximately 10(-41) atm at 1200 K) and is equivalent to that of Ti containing ∼2 mass% O at 1200 K. Therefore, when deoxidizing Ti to the commercial l...

For economical and ecological reasons, synthetic chemists are confronted with the increasing obligation of optimizing their synthetic methods. Maximizing efficiency and minimizing costs in the production of molecules and macromolecules constitutes, therefore, one of the most exciting challenges of synthetic chemistry.1-3 The ideal synthesis should produce the desired product in 100% yield and s...

Thermodynamic and electrochemical properties of actinides in molten fluoride salts are one the key data required for design safety assessment any salt reactor concept using liquid based fuel. In case Molten Salt Fast Reactor (MSFR), special attention has to be paid thorium fluoride, which is a direct fuel carrier constituent. This work presents experimental measurement ThF4 activity coefficient...

Abstract: composition of MgO and nano boehmite. The reactant and potassium chloride, as the reaction media, were fired at800-1000 °C at different dwell times (0.5-5 h) in the ambient atmosphere. After washing and filtration, the spinel nanopowder was characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Brunauer-Emmett-Teller (BET) techniques. It was demonstrated tha...

The modification of the fuel composition in a molten salt reactor can cause the precipitation of fissile materials and thus the generation of fissile lumps moving within the system and introducing localized perturbations of multiplicativity. The problem of reactivity oscillations connected to this phenomenon in circulating fuel systems is addressed. The periodic behavior of such reactivity inse...

There is increasing interest in using ionic molten-salt Flibe not only as self-cooled tritium(T)-breeding material in a fusion reactor blanket but also as fuel solvent of molten-salt fission reactors. Application of Flibe to T-breeding fluid for a stellarator-type fusion reactor operated at a high magnetic field brings large simplification of its blanket structure, allowing continuous operation...

Calcium hydroxyapatite (HA) whiskers and crystals were produced by the route of molten salt synthesis. The effects on whisker morphology of chosen flux, flux-to-HA ratio, synthesis temperature, and reaction time were investigated. The thermal stabilities of the produced whiskers were tested at 1300°C in an air atmosphere. A tentative X-ray diffraction pattern was proposed for the HA whiskers. M...

The molten-salt reactor (MSR) concept is one of the most promising systems for the realisation of transmutation. The objective is the development of a transmutational technique along with a device implementing it, which yield higher transmutational efficiencies than that of the known procedures. The procedure is the multi-step transmutation, in which the transformation is carried out in several...
