The AHTR is a pool-type reactor with graphite matrix coated-particle fuel and a clean molten salt coolant [1]. Due to the very high thermal inertia provided by the pool configuration and molten-salt coolant of the AHTR, the thermal power of the AHTR can be substantially higher than an equivalent gas-cooled reactor, likely exceeding 2000 MW(t). The AHTR, with a molten-salt intermediate loop and ...

Production of silicon film directly by electrodeposition from molten salt would have utility in the manufacturing of photovoltaic and optoelectronic devices owing to the simplicity of the process and the attendant low capital and operating costs. Here, dense and uniform polycrystalline silicon films (thickness up to 60 μm) are electrodeposited on graphite sheet substrates at 650 °C from molten ...

In this study, TiO2 nanoparticles (average particle size 16 nm) were successfully produced in molten salt phase and were showed to significantly enhance the specific heat capacity of a binary eutectic mixture of sodium and potassium nitrate (60/40) by 5.4 % at 390 °C and 7.5 % at 445 °C for 3.0 wt% of precursors used. The objective of this research was to develop a cost-effective alternate meth...

To identify the performance and mechanism of variant molten salts during biomass pyrolysis in salt, thermogravimetric differential scanning calorimetry (TG-DSC) analyzer, fixed-bed reactor thermodynamic equilibrium simulation were applied to study thermal melting characteristics stability salt as well selectivity for products. The KCl-ZnCl2 is appropriate preparation H2-rich gas carbon material...

In order to obtain molten salt with lower melting point, higher thermal stability and reduced cost relative to previously available materials, a variety of molten salt mixtures of alkali nitrates are investigated by experimental methods. However, since measurements are generally expensive and time-consuming, it is of interest to be able to predict melting point and the component of multi-compon...

Well crystallized pure calcium zirconate (CaZrO3 ) nanopowder was successfully synthesized using the molten-salt method. CaCl2 , Na 2CO3, micro-ZrO 2and nano-ZrO 2 were used as starting materials. On heating, Na2CO3 reacted with CaCl 2to form NaCl and CaCO 3. Nano CaZrO 3 was formed by reacting equimolar amounts of in situformed CaCO 3 (or CaO) and ZrO 2 in molten Na 2CO3-NaCl e...

Mesoporous SnO(2) agglomerates with hierarchical structures and a high surface area were fabricated through a molten salt method. The SnO(2) demonstrated high photoelectric conversion efficiencies of 3.05% and 6.23% (with TiCl(4) treatment) in dye-sensitized solar cells, which are attributed to its dual functionality of providing high dye-loading and efficient light scattering.

Well-crystallized Li2NiTiO4 nanoparticles are rapidly synthesized by a molten salt method using a mixture of NaCl and KCl salts. X-ray diffraction pattern and scanning electron microscopic image show that Li2NiTiO4 has a cubic rock salt structure with an average particle size of ca. 50 nm. Conductive carbon-coated Li2NiTiO4 is obtained by a facile ball milling method. As a novel 4 V positive ca...

Two new concepts have been identified for direct steam generating solar fields that charge a two-tank molten salt storage system. The use of both supercritical and superheated subcritical steam is proposed, and discussed in practical terms and with regards to thermodynamic issues of heat transfer to the salt. Both concepts are found to allow significantly higher hot-tank temperatures than solar...
