Abstract
Results of a study of the thermal stability of advanced bottom blocks simulated for operating under critical conditions are reported. The thermal stability of domestic N-3-grade bottom blocks made up of composite carbon materials subjected to radial temperature gradients generated by local current heating is shown to be not inferior to that of foreign analogs. The thermal stability is shown to correlate with electric resistivity and rupture strength of the material
