Refractury materials

The Celts used graphite to produce particularly fire-proof crucibles more than 2000 years ago. Because graphite is resistant to oxidation, offers good thermal conductivity and is also chemically inert, this raw material still plays an important role in the refractory industry today – e.g. in magnesite bricks for lining furnaces or coverings for high-quality metal melts to prevent oxidation. Large-flake graphite with a well-developed crystal structure is used for the production of refractory materials. It dissipates heat, yet can withstand very high temperatures and guarantees a long service life for the product.
