The invention discloses a crucible, an induction coil for a cavity of the crucible and material processing equipment. A heating cavity is defined by the cavity, the induction coil surrounds the heating cavity to generate a magnetic field for heating materials in the heating cavity, the induction coil is provided with a first coil assembly, a second coil assembly and a third coil assembly which are distributed in the vertical direction, and the second coil assembly is located between the first coil assembly and the third coil assembly. The first coil assembly, the second coil assembly and the third coil assembly each comprise a plurality of turns of sub-coils distributed in the vertical direction, and the turn pitch of the first coil assembly and the turn pitch of the third coil assembly are smaller than the turn pitch of the second coil assembly. According to the crucible, the induction coil for the cavity of the crucible and the material processing equipment, the temperature distribution of the heating cavit
