The invention discloses a heterogeneous multi-layer crucible. The heterogeneous multi-layer crucible comprises a plurality of crucible layers made of different materials, and a sand filling layer is arranged between every two adjacent crucible layers. The heterogeneous multi-layer crucible further comprises a first crucible layer (1), a second crucible layer (3) and a third crucible layer (5), wherein a sand filling layer I (2) is arranged between the first crucible layer (1) and the second crucible layer (3), and a sand filling layer II (4) is arranged between the second crucible layer (3) and the third crucible layer (5). Compared with the prior art, the heterogeneous multi-layer crucible is characterized in that the crucible has multiple layers and is made of different materials, the material with the melting point slightly lower than the boiling point of a material to be heated can be used, the material with a high melting point is not needed, production cost is lowered, and the problems of vessels needed by heating, melting, boiling and volatilization of materials with a high melting point and a high boiling point is resolved. The number of layers and materials of the crucible can be increased and selected according to the needs, the service life is prolonged, and industrial production is facilitated.
