Title: High-Pressure Studies on Synthetic Orthorhombic Cubanite (CuFe{sub 2}S{sub 3})

Abstract

We report here the successful synthesis of orthorhombic cubanite using microwave heating and characterization for its orthorhombic phase by powder X-ray diffraction, Micro-Raman, Thermal and high pressure electrical resistivity measurements. The unique physico-chemical conditions prevent successful synthesis under laboratory conditions, however the mineral occurs in nature in its orthorhombic form. A distinct endothermic dip in Differential Thermal Analysis (DTA) at 280 deg. C is in agreement with the DTA data reported for natural cubanite. An irreversible first order phase transformation from orthorhombic to NiAs structure is seen at 4 GPa/200 deg. C. High pressure electrical resistivity and micro-Raman spectroscopic measurements on the synthetic sample exhibit transformation to isocubanite.
