  • Systems and methods for production of silicon using a horizontal magnetic field
    Patent number: 11932962
    Abstract: A method for producing a silicon ingot by the horizontal magnetic field Czochralski method includes rotating a crucible containing a silicon melt, applying a horizontal magnetic field to the crucible, contacting the silicon melt with a seed crystal, and withdrawing the seed crystal from the silicon melt while rotating the crucible to form a silicon ingot. The crucible has a wettable surface with a cristobalite layer formed thereon.
