Menshikovite, Pd-Ni arsenide and synthetic equivalent

Abstract

AbstractThe average compositions of menshikovite (Pd3Ni2As3) from the type locality (Lukkulaisvaara layered intrusion, Russian Karelia) and a Pd-Ni arsenide synthesized at 450°C, are very close. The observed ΣMetal:As ratio is close to 5:3, as in the case of previously described arsenides from the Stillwater and Two-Duck Lake intrusions. The compositions suggest that these unnamed Pd-Ni arsenides and the synthetic phase are in fact menshikovite.
