Abstract: We have obtained observations of six symbiotic stars with Spitzer MIPS (photometery at 24 μm and 70 μm) and IRS (spectroscopic range 9.9–37.2 μm). Here we report the presence of 10 μm and 18 μm dust features in one of these stars, BI Cru, which were not observed in ISO spectra of the same system.
