Preparation of single crystals of binary and ternary transition metal and uranium arsenides and antimonides from reactive-fluxes

Abstract

Single crystals as large as 2 mm of binary transition metal and uranium arsenides and antimonides can be grown from the reactions of titanium, chromium, zirconium, hafnium, tantalum, rhenium, or uranium with alkali metal arsenides and antimonides from 500°C to 950°C. Single crystals of the ternary uranium copper arsenide phases UCuAs 2 and U 2Cu 4As 5 can also be grown from the reaction of uranium and copper with Cs 3As 7. The resulting crystals were analyzed by electron dispersive analysis by X-rays (EDX) and single crystal X-ray diffraction.
