Zusammenfassung:A crucible assembly and a thermal field assembly, the crucible assembly comprising a crucible holder; a crucible slope which is arranged on the crucible holder, the crucible slope having a crucible mounting cavity that gradually expands from the crucible holder in a direction away from the crucible holder; and a crucible which is arranged in the crucible mounting cavity, an outer side surface of the crucible being an outer side surface that gradually increases from the crucible holder in the direction away from the crucible holder, the outer side surface being arranged opposite an inner side surface of the crucible mounting cavity, and the crucible slope having a softening temperature higher than that of the crucible. According to the above solution, the crucible slope and the crucible can easily be separated, thereby avoiding damage to the crucible slope and improving the production safety.
