Blanco, V. Orofino, M. Martino, S. Fonti, J. Stephens] Summary: The mass absorption coefficients of some glassy and crystalline silicates of astrophysical relevance have been measured. We produced and characterized also synthetic silicates of olivine type since this material is considered one of the most likely components of cometary dust grains. The experimental data are used to fit the emission feature observed in the Comet Halley spectrum between 8 and 13 urn. Satisfactory results are obtained by using synthetic olivine mixed with a small amount (5%) of crystalline grains.
