Abstract

Classical nucleation theory must be modified for the condensation of small, solid dust grains. Ion nucleation is unimportant and exchange reactions with gas molecules are required. For carbon-rich stellar atmospheres, hydrocarbons act as intermediaries for converting acetylene gas into carbon particles. For oxygen-rich atmospheres, magnesium silicate grains form by surface nucleation. Sputtering and coalescence of grains is discussed.
