Abstract

Neutron powder diffraction data and the Rietveld method were used to refine the crystal structure of fibrolitic sillimanite. Lattice and structural parameters of the refined structure were found to correlate with previously reported data for sillimanite. The fibrolite was further observed to have tertrahedral site occupancies. A small amount of isotropic strain broadening was also seen. Results also indicate that the observed tetrahedral disorder is not caused by an equilibrium disordering process.
