The crystal growing unit has a first thermal insulation with a first thermal conductivity and a second thermal insulation with a second thermal conductivity. The crucible has a crucible base, a crucible side wall and a crucible cover. The crucible side wall is indirectly or directly surrounded by the first thermal insulation. The second thermal insulation is arranged indirectly or directly above the crucible cover. The second thermal conductivity is greater than the first thermal conductivity.
