The B[e] phenomenon is associated with early-type stars, in whose spectra low-excitation forbidden line emission and strong infrared excess due to radiation of circumstelar dust are simultaneously present. It is associated with objects at different evolutionary stages, ranging from the pre-main-sequence to the planetary nebula stage. Only two groups of them, B[e] supergiants and FS CMa type stars, seem to currently produce new dust, while those of all other types inherit dust from previous evolutionary stages. The recently defined Galactic FS CMa group comprises nearly 40 not very luminous objects that significantly expanded the luminosity range of hot dust-forming stars. Here we report the first results of infrared spectroscopy of these objects obtained with Spitzer Space Telescope IRS. Properties of the dust that we extract from these data provide new information about the objects' intrinsic parameters, which are still poorly known.
