FIELD: electric heating elements.
SUBSTANCE: electric heating element, a high-pressure cell, and a method for producing and/or processing a superhard material by high-pressure and high-temperature methods are proposed. The high pressure cell (HPC) contains an electrical heating element made of at least one electrically conductive material and at least one non- electrically conductive material, wherein the mass ratio of said at least one electrically conductive material to said at least one non- electrically conductive material changes in the electrical heating element along at least one direction, wherein the non-conductive material contains a metal oxide.
EFFECT: invention ensures the creation and maintenance of the specified parameters of the temperature field with the necessary temperature gradients in the HPC.
