Zirconium Diboride (ZrB2) powder was synthesized at low temperature via a Direct Molten Salt Reaction (DMSR) method. The influence of different salt compositions including eutectic mixture of (KF-NaF), (KF-KCl) and (KCl-NaCl) on the morphology and purity of the reaction products was studied. The obtained samples were characterized by scanning electron microscopy (SEM) and X-ray diffraction (XRD...

The oxide fuel reduction process, based on an electrochemical method as well as the long-lived radioactive nuclides partitioning process based on pyroprocessing, which are being developed at the Korea Atomic Energy Research Institute (KAERI), are to generate molten salt wastes such as a LiCl salt and a LiCl-KCl eutectic salt, respectively. The treatment process of waste LiCl salt, consisting of...

Practical implementation of one-dimensional semiconductors into devices capable of exploiting their novel properties is often hindered by low product yields, poor material quality, high production cost, or overall lack of synthetic control. Here, we show that a molten-salt flux scheme can be used to synthesize large quantities of high-quality, single-crystalline TiO2 nanowires with controllable...

This study focuses on the optimization of an electric heater design for molten salt pre-heating in a supercritical CO2–molten-salt loop. The scope investigation is to analyze typical designs similar components identifying possible malfunctions and defining proper modifications geometry operating conditions address such technical issues optimize attained thermal efficiency. By performing computa...

This paper describes progress towards a first-of-a-kind demonstration of an integrated solar dish and moltensalt storage system, using the superheated steam energy transport concept developed by Wizard Power. Superheated steam is used to charge an energy storage system with a single sensible-heat-storage medium (in this case molten salt), by restricting the steam conditions to the superheat reg...

Chemical incompatibility and low thermal conductivity issues of molten-salt-based thermal energy storage materials can be addressed by using microstructured composites. Using a eutectic mixture of lithium and sodium carbonates as molten salt, magnesium oxide as supporting material, and graphite as thermal conductivity enhancer, the microstructural development, chemical compatibility, thermal st...

In this study, a novel chlorination technique for metallic titanium (Ti) was devised in order to establish a recycling process that uses both Ti metal scrap and iron chloride (FeClx) waste, and its feasibility was demonstrated. Direct reaction between Ti and FeClx has drawbacks such as slow kinetics of Ti chlorination and high volatilization of FeClx. To overcome these, the authors proposed a c...
