Intention and Scope ….
The European Course on Carbon Materials addresses students from the areas of chemistry, physics, material science, chemical engineering but also engineers in construction, automotive and aviation. Interested persons from commercial areas will find this basic and comprehensive introduction into industrial carbon materials of high interest.
Industrial carbon materials, although not well known to the public, are essential for the operational capability of a modern economy. The annual production of about 1.7 billion tons of steel requires carbon and graphite bricks for the blast furnace. The melting of steel scrap is the biggest recycling process on earth. It produces about 400 million tons of recycled steel under the consumption of 1.1 million tons of graphite electrodes. Aluminum is a light metal with gaining importance in light weight construction. The annual production of 52 million tons of primary aluminum in the Hall-Héroult electrolysis requires more than 24 million tons of calcined petroleum coke.
Beyond these fields of base metal production fine grained graphite has many facets of applications. These applications reach from non-ferrous metallurgy, glass production, components for the production of mono- and polycrystalline silicon, susceptors for silicon epitaxy, solar wafer production, nuclear application, electrical discharge machining, to applications in high temperature furnace technology as susceptors and crucibles. Last but not least, specialty graphite is important for chemical analysis methods and medical technology.
The participants will learn about the raw materials, the manufacture of granular carbon materials and their specific application. Synthetic carbon and graphitized materials are the result of thermal conversion processes. Thus more information will be given about their basic reactions and principles.
Most of the industrial carbon and graphite materials are synthesized form carbonaceous precursors. But also natural graphite is an important raw material. The majority of natural graphite is still consumed for refractory applications. However its use as anode material in lithium-ion batteries is fundamental for electro-mobility.
Activated carbons with their high specific surface area are indispensable for air and water cleaning processes. Furthermore the high surface area enables the use in electric double layer capacitors (EDLC´s).
Carbon black is with us whenever we ride in an automotive. Beyond the use in tires and rubbers, carbon black is as a pigment responsible for the most brilliant black paint.
Global warming discussion drives the effort and investment into light weight construction. Carbon fibres combine highest specific strength and stiffness and thus are predestinated for the use in automotives and aviation. Construction with carbon fibres reinforced concrete opens new spectacular design opportunities in buildings.
The reaction of carbon with its next group neighbour in the periodic system, silicon to silicon carbide extends the way into ceramics. The control over the high brittleness of ceramics can be achieved by the reinforcement of SiC with carbon fibres (CSiC). Areas of application are wear components and ballistic protection systems.
Many physical properties of graphite are not yet sufficiently used. Better use and new, huge fields of application can be generated with nanoforms of the element carbon. This comprises fullerenes, single- and multiwall nanotubes, graphenes and other nanoforms. Most promising fields of application are in electronics, sensor technology, medical and also mechanical applications.
The organizers present with pride the most experienced speakers from industry and academia on these manifold aspects of industrial carbon and graphite materials.
