The application of variable atmosphere thermomagnetometry to the thermal decomposition of pyrite
Thermomagnetometric studies of pyrrhotites, Fe(1−x)S, formed during the decomposition of pyrite, were made in dry, oxygen-free nitrogen, 3% hydrogen in nitrogen, and 1.2% oxygen in nitrogen. Decomposition was demonstrated to be more complex than could be determined by thermogravimetric measurements. X-ray powder diffraction techniques, or chemical analysis of quenched pyrite samples. Thermomagnetometry was shown to be a sensitive and useful technique, enabling the detection of a number of magnetic phases within the decomposition products.
