1. November 22, 2005 German Press Release - Contract with PBMR




                                                                       EXHIBIT 1

SGL Signs Contract with PBMR

o    Cooperation with South African Nuclear Energy Company Goes Forward

WIESBADEN, November 22, 2005. SGL Carbon and the South African nuclear energy
company "Pebble Bed Modular Reactor" PBMR (Pty) Ltd. have signed a major
contract in Pretoria. This agreement is under the framework of cooperation in
the construction of pebble bed modular reactors in South Africa, which was
announced on August 22, 2005. The partial agreement covers the production of
graphite for a demonstration reactor that is to supply electricity beginning in
2011.

PBMR is owned by a consortium comprising the largest South African energy
supplier, Eskom, as well as the state-owned development finance institution
Industrial Development Corporation of South Africa (IDC), and British Nuclear
Fuels (BNFL). PBMR has the ambition to construct commercially operating pebble
bed modular reactors for electric power generation in South Africa beginning in
2013. As an alternative to non-renewable fossil fuel resources, PBMR technology
is to be utilized in the near future as a low-cost, CO2-free form of energy
production.

PBMR selected SGL Carbon as a strategic supplier because of the latter's
expertise in the production and development of highest quality graphite. The two
companies have been working together for a number of years on the development of
materials for use in PBMR technology. The planned construction of a
demonstration reactor in South Africa beginning in 2007 could translate into
sales of (euro) 35 to (euro) 40 million during the period 2006 to 2008 for the
Specialties Business Unit of SGL Carbon. Additional information about PBMR is
available at www.pbmr.co.za.
