Summary: AEROSOLS
Micron- cosmic analogs subcategories
Circumstellar shells
Lunar dust
Origin
provided by Kemira Pigments Oy, Pori, Finland
Main constituent
titanium oxide, TiO2
Practical significance
rutile dust particles are thought to be the most likely nucleation seeds in oxygen-rich circumstellar shells (Jeon et al. 1999, 2003). In addition,rutile is an accessory component of the lunar regolith (Frondel1975).
