AbstractThe far-infrared extinction of various silicates was measured in the 27 - 400 μm range of wavelength. The SiO2content of our samples distributes between 45 and 100 weight (wt.)%. There is no distinct absorption band in the far-infrared region and the extinction decreases in proportion toλ−1.4.
