摘要

Pyrite (FeS2) crystals doped with As, Ni and Co were synthesized with chemical vapor transport over an 18 cm horizontal gradient of 700-600 degrees C in evacuated quartz tubes, from a mixture of Fes and S, with FeBr3 as a transport agent. Sulfur fugacity and thus S:Fe stoichiometry was constrained by the Fe1-xS/FeS2-y buffer. As, Ni and Co concentrations were similar to 3-800ppm, similar to 200-1500 ppm and 450-3700 ppm, respectively.
