The low temperature electrochemical growth of iron, nickel and other metallic single crystals from halide eutectic fluxes in a temperature gradient

• Single crystals of pyre metallic Fe, Ni, Co, Cr, Al, Cu, Ag, Au, Pd, Pt and a few alloys were grown.
• We used the AlCl3/KCl and CsCl/NaCl/KCl fluxes and a permanent temperature gradient.
• The presence of a conducting wire was found to be necessary for metal transport.

Single crystals of metallic Fe, Ni, Co, Cr, Al, Cu, Ag, Au, Pd, Pt and a few alloys were grown using the AlCl3/KCl and CsCl/NaCl/KCl fluxes for Men+ transport and an inert metallic wire for electron transport in a permanent temperature gradient from 350–600 °C that produced single crystalline samples with dimensions of approximately 2×2×2 mm3. Energy dispersive X-ray spectroscopy established crystal formation of pure metals.
