Preliminary results of infrared observations from 2.3 up to 10 and 20 microns of the Be-X-ray stars X Per, Gamma Cas and HDE 245770, indicate the presence of an ionized circumstellar disk with an electron density law of the type where ne varies as r to the -3.5 power. X Per and Gamma Cas also show besides, variable infrared excess at 10 microns suggesting variability in the stellar wind. LS I+65 deg 010 presents an anomalous infrared energy distribution for a Be star.
