  Ceres is the largest body in the Main Belt, and it is characterized by a
large abundance of water ice in its interior. This feature is suggested by its
relatively low bulk density (2162 kg m$^{-3}$), while its partial
differentiation into a rocky core and icy crust is suggested by several
geological and geochemical features: minerals and salts produced by aqueous
alteration, icy patches on the surface, lobate morphology interpreted as
surface flows. In this work we explore how the composition can influence the
characteristics of thermal convection in the crust of Ceres. Our results
suggest that the onset of thermal convection is difficult and when it occurs it
is short lived and this could imply that Ceres preserved deep liquid until
present, as recent suggested by the work of Castillo-Rogez et al.. Moreover,
cryovolcanism could be driven by diapirism (chemical convection) rather than
thermal convection.
