Low resolution ISOPHOT-S spectroscopy (2.5 - 5, 6 - 12 
m) has been used
to observe several oxygen-rich and carbon-rich stars in order to gain
information about the the composition of the dust present around these stars.
Spectra of R CrB have been obtained, near minimum and about 10 months later,
showing the change in the intensity of a plateau-like feature between 6 and
8m.
