Extinction coefficients from 7 to 140 microns are reported for three kinds of hydrous silicates, montmorillonite, chlorite, and serpentine. In the far infrared, montmorillonite shows no remarkable absorption feature, while chlorite has a broad bump with two wide peaks at 72 and 85 microns. Serpentine shows the steepest wavelength dependence with two small peaks. In the mid-infrared, montmorillonite shows a very broad band with the center at 9.66 microns and a weak asorption peak at 10.95 microns. Chlorite exhibits a brand band at 10.3 microns and a weak peak at 11.36 microns, and serpentine has two clearly separable bands at 9.3 and 10.15 microns. The effect of heating on mid-infrared extinction features was studied. Montmorillonite fine structures disappear by heating while for chlorite more new peaks appear with higher temperature comma. For serpentine, many new peaks appear and the spectrum resembles that of olivine. Implications of the results for studies of M-type stars and cometary dust tails are discussed.
