Crucibles and Refractory Products
A history dating back millennia
The Celts used graphite in the production of fireproof ceramics more than 2,000 years ago. Graphite still plays an important role in today's fireproofing industry thanks to its high resistance to oxidation, its outstanding thermal conductivity and its chemically inert behaviour.
Large flake graphite with a well-pronounced crystal structure is a guarantee for long service life and high-quality crucibles, where graphite also reduces the formation of deposits and slag. Graphite is also used as covering material for high-quality molten metal – for instance, high-purity flake graphite is used in copper production.
Graphite is an important component of many fireproof materials primarily used in the metal production industry. In magnesite bricks for furnace lining, continuous casting gutters and mould compounds, graphite is a highly-resistant thermal conductivity additive and a crucial part of ceramic formulas.
