ABSTRACT:
A zig-zag picket type graphite heater for use in high temperature furnaces such as are used for crystal growing, for example, is constructed by forming and zig-zag slotting a cylindrical shell-like element. The cylindrical element is then cut into a plurality of like, discrete segments by extending selected ones of the slots through the entire length of the element. Graphite connector elements are then secured between the segments to connect the segments, and also function as connectors to an electric current supply line.
