Bar chart depicts the cathode producers and their capacity. Graph depicts the increase in cell amperage over the last seventy years. Photo depicts the test assembling of a blast furnace lining. Bar chart depicts the hot metal production in blast furnaces. Graph depicts the blast furnace diameter. The furnace size is referred as the diameter of the heart increased from a few meters up to 15m. Schematic illustration of the silicon single crystal production. Bar chart depicts the demand for fine-grained graphite. Bar chart depicts the fine-grained graphite producer.

      The mechanical strength is the key quality parameter for iso‐graphite. Fundamentally the strength of graphite increases with decreasing grain size. This led to a decrease in grain size during the last decades to nowadays few microns and mechanical strength of up to 100 MPa. The future challenging task is the process technology and automation to produce bigger block sizes at high process yield.

      It was shown that traditional carbon and graphite materials have a long‐lasting history. During this history they have improved their quality and reliability. Their consumption in their respective application was reduced. Despite this long history there is still room for improvement and open questions for basic research. The industrial perspectives for these materials are prosperous. The most probably ongoing growth in the BRIC countries will provide a constant grown in the demand for graphite electrodes, cathodes, and furnace linings. Iso‐graphite will benefit from the global expansion of clean solar energy.
