About Kaisersberg
Grafitbergbau Kaisersberg GmbH, headquartered in St. Stefan ob Leoben (Styria, Austria), is one of the few graphite producers in Europe with its own mining operations and runs the only active graphite mine in the Alps. Underground, microcrystalline graphite is mined from a depth of around 800 meters and processed in-house into ultra-fine milling grades up to granular graphites. The product range includes microcrystalline graphite, flake graphite, synthetic graphite and expandable graphite with carbon contents from 40% to over 99%, complemented by special blends tailored to customer requirements. The graphites are used, among other things, in the automotive industry, for battery applications, in fire protection and in lubricants. In addition to mining and milling, the company offers research and development, laboratory and quality management, technical consulting as well as warehousing and logistics with deliveries in bags, big bags, containers or by silo truck. The company premises are directly connected to the Styrian rail network, enabling deliveries worldwide.

Graphites and Products
Microcrystalline graphite (crystalline/amorphous graphite)
Natural material from our own mining operation, available as ultra-fine milling grades up to granular graphite with carbon contents from 40% to over 90% as well as in special blends.
Flake graphite
From large flakes to ultra-fine milling grades with carbon gradations from 70% to 99.9%, with raw material and processing adjusted according to the application.
Synthetic graphite
Artificially produced graphite in the form of highly pure ultra-fine milling grades for special applications.
Expandable graphite
Available with different expansion rates, pH values, particle sizes and onset-of-expansion temperatures and usable as a tailor-made blend, e.g. in fire protection.

History
- 1755
According to archival records, graphite has been mined in Kaisersberg since 1755; the operation has been privately owned throughout.
- 1990
Since the 1990s, in addition to traditional raw material mining, the development of new application areas has been particularly promoted.
