Abstract: Methods of recovering hydrohalosilanes from reaction residues are disclosed. An inorganic halosilane slurry comprising (i) tetrahalosilane, trihalosilane, dihalosilane, or any combination thereof, (ii) silicon particles, and (iii) heavies is passed through a thin-film dryer to remove halosilanes and form a solid residue comprising silicon particles. Heavies also may be removed as the slurry passes through the thin-film dryer.
