We investigate the mineralogy of dust around evolved stars in the Large Magellanic Cloud (LMC), in order to understand dust formation around these stars, the enrichment of the interstellar medium, and the nature of the dust that eventually goes into new planetary systems. The known distance and metallicity (Z) of the LMC provide a unique opportunity to study the effect of chemistry, density and Z on the dust formation process. Here, we present 7-14 μm Infrared Space Observatory (ISO) spectroscopy of 12 M-type evolved stars in the LMC, in order to study the dust mineralogy and condensation process around these stars. Also we discuss the ISO spectrum of the LMC Red Supergiant WOH G064, and the Spitzer Space Telescope spectrum of the LMC carbon star IRAS 04496-6958.
