Thermal Expansion of Troilite and Pyrrhotine in Helium and Air

Inorganic Materials Aims and scope

Abstract

High-temperature x-ray diffraction is used to determine the lattice parameters of synthetic troilite (sealed-ampule method) and pyrrhotine prepared via thermal dissociation of natural pyrite. The results are presented in the form of best fit polynomials in temperature. The gaseous environment (helium or air) is found to have a significant effect on the temperature variation of the lattice parameters.
