Exhibit 1

SGL Carbon increases Graphite Electrode Prices

Wiesbaden, May 31, 2005. SGL Carbon announces today new prices for its Graphite
Electrodes effective June 4, 2005 for all new businesses in:

Americas, Asia (excluding China*), Near Middle East and Africa:

o        For regular-sized Graphite Electrodes:      1,86  US$/lb (4100 US-$/mt)
o        For extra-sized Graphite Electrodes:        2,02  US$/lb (4450 US-$/mt)

Europe:
o        For regular-sized Graphite Electrodes:      3000 (euro)/MT
o        For extra-sized Graphite Electrodes:        3270 (euro)/MT

Regular-sized is defined as: Diameter 14" (350 mm) - 24" (600 mm)
Extra-sized is defined as: Diameter 26" (650 mm) - 30 " (750 mm)

These prices will be applicable for all orders received between June 4th, 2005
until October 31st, 2005 and for shipments effected prior to December 31st,
2006.

The demand for graphite electrodes remains at very high levels. The ongoing high
global production level for EAF steel is maintaining a tight supply/demand
balance for graphite electrodes. It is anticipated that this situation will not
change in the near future. SGL Carbon's 2005 order book for graphite electrodes
is full, requiring our plants to run at capacity.

For 2006, SGL plans to run at a production level that will support the announced
price increases. The price increases for graphite electrodes are required due to
continued pressure on our manufacturing facilities caused by the high
utilization rate, increased cost for all raw materials and energy, as well as
higher operating expenses, higher logistic costs and the impact of the volatile
exchange rates.

*Pricing in China is the sole responsibility of the joint venture between SGL
Carbon and Tokai in Shanghai (STS).

Exhibit 2



Ad hoc notification pursuant to  ss. 15 of the German Securities Trading Act
(Wertpapierhandelsgesetz)

SGL Carbon and Audi Sign Cooperation Agreement on Carbon-Ceramic Brake Discs

Wiesbaden, June 7, 2005. SGL CARBON AG, Wiesbaden, and AUDI AG, Ingolstadt, have
signed a cooperation agreement on carbon-ceramic brake discs (CCB). Within the
scope of this agreement, SGL Carbon will receive a low double-digit million Euro
amount for technological and manufacturing developments as well as for the
planning of automated serial production.

An additional feature of the cooperation between SGL Carbon and Audi is a
possible mutual investment into a large-scale serial production resulting from
the development agreement. This could take the form of a joint venture.
Decisions on this will, however, be made at a later date.

Meanwhile, Audi will introduce the CCB into the market within the scope of a
long-term supply agreement. The discs will be supplied by the existing SGL
Carbon production facilities in Meitingen.

This cooperation agreement is subject to the approval of the necessary bodies
which is expected to follow over the next few weeks.

With these measures, Audi is supporting the technological and commercial
advancement of this technology developed by SGL Carbon in the 90ies and brought
to serial development with Porsche. This cooperation agreement allows Audi to
secure the necessary prerequisites to use these innovative materials in its
future programs.

In this context and as an initial step, Audi is introducing its new Audi A8 W12
Quattro with the CCB today in the new Allianzarena in Munich. Upon request by
the customer, this flagship of the Audi brand will be equipped with the new
brake disc from Autumn 2005 onwards.
