Graphite is produced from powder as a carbon source by means of a graphitization furnace. The graphitization furnace is comprised of: an electrically conductive crucible including a hollow configured to house the powder; an electrode including a columnar shaft and a head provided at an end of the shaft, the head having a shape selected from the group consisting of a sphere, a hemisphere, a column with a rounded edge, a cone, and a cone with a rounded tip; and a power source configured to apply electric current to the powder through the crucible and the electrode.

Graphitization furnace and method for producing graphite

A graphitization furnace () includes: split electrodes () that are conductive and are provided so as to be freely movable; crucibles () that are conductive and that contain carbon powder, with a bottom end portion () of each split electrode () being buried in the carbon powder; upper electrodes () that are positioned so as to face a split electrode (); lower electrodes () that are positioned so as to face a crucible (); and a power supply unit () that, when a bottom end portion () of an upper electrode () is placed in contact with a top end portion () of a split electrode () and a top end portion () of a lower electrode () is placed in contact with a base portion () of a crucible (), applies a voltage between the upper electrode () and the lower electrode ().
