A high-speed high temperature electrical resistance heater and method of making the same, said heater being in the form of a uniquely configured composite, non-homogeneous body having an esentially electrical-conducting material and an essentially electrically insulating material, wherein one of the materials is constituted as a porous matrix, and the other of the materials permeates the matrix of the one material. The electrically-conducting material has nodes and connective threads interconnecting the nodes, and electrical connections can be made to different places on the electrically-conducting material. The method involves forming a sintered matrix and impregnating the same with a ceramic substance, then sintering the impregnated matrix.
