The study of the interstellar extinction and of the spectral features (absorption/emission) in the infrared, observed in astronomical spectra, provides indications about likely material candidates for cosmic dust. Carbonaceous materials as silicon carbide, amorphous carbon, also in hydrogenated form (HAC), and mixtures of HACs with PAHs (polycyclic aromatic hydrocarbons) have been studied in the laboratory under carefully controlled experimental conditions. The authors present here the most relevant results obtained in their laboratory work, and compare their data with similar results of other authors.
