Nanocrystalline chromium disilicide synthesized by a fast Chlorine-Transfer-Reaction

Recent Developments on Molten Salt Synthesis of Inorganic Nanomaterials: A Review

“…There is another work on the MSS of highly complex high entropy silicide nanopowder (Nb 0.25 Ta 0.25 Ti 0.25 Hf 0.25 )­Si 2 . Godfroy et al synthesized CrSi 2 NPs using the reaction between CrCl 3 and Si in the presence of NaCl–LiCl salt to reduce the particle size . As an important functional material, MoSi 2 NPs were successfully synthesized by Nersisyan et al using the NaF molten salt .…”

Converting silicon nanoparticles into nickel iron silicide nanocrystals within molten salts for water oxidation electrocatalysis

“…These reactions have been well explored by chemical vapor deposition (CVD) to yield metal silicide nanowires 25,26,28,[39][40][41][42] usually at ca. 900 C. 26,42 The same reaction has been performed in the solidstate and in molten salts for CrSi 2 at 800 C. 43,44 This temperature is poorly compatible with the recovery of high surface area nano-objects, because of the extensive growth of these particles at high temperature. To decrease further the reaction temperature, we have used a molten salt medium to ensure liquidphase reaction, and 40 nm silicon nanoparticles (diamondlike crystal structure, denoted as d-Si) as reagents with enhanced reactivity compared to bulk silicon.…”

Geoinspired syntheses of materials and nanomaterials

“…Again, alkali halides are adequate molten media to trigger the reaction between oxygen-sensitive silicon sources and metal precursors. While the latter are usually metal halides, 204,212 as for most of the materials families described above, there are only a few available Si sources that can operate at temperatures between 300 and 800 1C and be maintained in a liquid medium without the need of pressurized vessels. Elemental silicon powders have been used to produce CrSi 2 , 212 while silica has been combined with molybdenum oxide to form MoSi 2 nanostructures by exothermic magnesiothermal reduction in molten NaF.…”
