Oxide/oxide ceramic matrix composite “Keramikblech”
The technical ceramic for high temperature applications for industry and research
named “Keramikblech” (sheet ceramic) is an oxide fiber reinforced oxide ceramic, a part of the material group called ceramic matrix composites. This material is an advanced technical ceramic for developers, designers and users, who want to design thin walled, thermal shock resistant
and oxidation resistant ceramic components for continuous service temperature up to 1300°C. “Keramikblech” replaces thermal and mechanical highly loaded sheet metal components, which should not be distorted or should not be oxidized.
Components that have performed well:

• production parts for aluminum casting
• furnace components like furnace doors, furnace linings, hot gas butterfly valves, sintering aids
• burner tubes, flame tubes, burner components and combustion chambers
• structures for extreme thermal shock
• special components for aeronautics and astronautics

Unique feature of oxide/oxide ceramic matrix compositewerkstoffen

• long term operation up to 1300°C
• high strength at high temperatures
• high mechanical load by the use of the textile ceramic composite
• pseudo elastic behavior
• very good thermal shock resistance
• very good oxidation resistance at high temperatures
• good corrosion resistance at high temperatures
• good hardness
• low thermal expansion – about 50% of stainless steel
