Intelligent Alternatives to Metals and Plastics
New procedures and production technologies today require the use of highly wear-resistant components. They must be able to withstand mechanical and chemical attacks or operate reliably on a low-maintenance level in high-frequency ranges.
Thanks to their diverse properties, ceramics have become an increasingly popular alternative to metals and plastics.
We offer our customers products made to measure, for application in areas with those specific conditions. Our customers can rely on our expertise in construction, material selection and production techniques that stems from 120 years of experience in the industry. We offer a varied range of silicate and oxide ceramics with different material systems and their modifications. Our own mould and prototype construction facilities provide an important foundation for the optimal use of our casting technology.
Finishing processes like grinding, cementing, gluing, reinforcing or metallising provide a wide range of possibilities for shaping and completing of the ceramic components.
Also items manufactured in small batches, or even individually, are likely to make economic sense because of their high wear, temperature and deformation resistance.

• Ceramic materials exhibit very high mechanical strength which is required for the application as components for machines and equipments.
• The hardness of advanced ceramic materials is above 9 on Moh´s Scale, and only diamond is harder (which rates 10 on Moh´s Scale). For this reason ceramic materials are excellent suitable for the production of parts with very high wear resistance e.g. for the paper-, textile- and wire industry.
• The low density of the ceramic material is advantageous in the design of rotating movable parts such as bearings, valves, and rotors.
• Ceramic materials are extremely heat resistant. The properties of metals can be significantly above 500 ° C after. Construction ceramics, however, can also be used above 1000 ° C. Ceramic components, for example in the metal industry in direct contact with molten metal (eg Abziehringen) is used.
• In contrast to metals ceramic materials react only insignificant with acids and bases. Therefore they are ideal for the application in chemical industry.

Moreover, ceramic materials are bioinert and are used as implants (e.g. hip joint endoprosthesis, tooth pins, malleus).
All ceramic materials (also non-oxide) exhibit excellent oxidation resistance at high temperatures.

Ceramic Part
Material Definition & Classification
Industrial ceramics are inorganic, non-metallic materials engineered for extreme environments. Primary categories include:
Oxide Ceramics: Al₂O₃ (alumina), ZrO₂ (zirconia)
Non-Oxide Ceramics: SiC (silicon carbide), Si₃N₄ (silicon nitride)
Composite Ceramics: ZTA (zirconia-toughened alumina), AlN (aluminum nitride)

2. Core Properties
Mechanical: Vickers hardness up to 2,500 HV (SiC), flexural strength exceeding 1,200 MPa (Y-TZP zirconia)
Thermal: Thermal shock resistance (ΔT> 500°C for Al₂O₃), low CTE (4×10⁻⁶/°C for Si₃N₄)
Electrical: Dielectric strength> 10 kV/mm (99.6% alumina), semiconductor behavior (SiC)
Chemical: Inert to acids/alkalis (except HF for SiO₂-based ceramics)
3. Manufacturing Processes
Forming: Dry pressing (for simple geometries), injection molding (complex shapes), slip casting (large components)
Sintering: Conventional (1,600°C for alumina), HIP (hot isostatic pressing for pore-free structures)
Finishing: Laser machining (±0.01 mm tolerance), diamond grinding (Ra < 0.1 μm)

‌Thermal Management Systems‌
Alumina (Al₂O₃): Insulating substrates for power electronics (e.g., IGBT modules) with CTE matching capabilities (7.2×10⁻⁶/°C)
Aluminum Nitride (AlN): High thermal conductivity (180 W/m·K) for LED heat sinks in automotive lighting
‌Mechanical Wear Resistance‌
Zirconia-toughened alumina (ZTA): Mining equipment liners with 3× longer service life than manganese steel
Silicon Carbide (SiC): Seal rings for chemical pumps, achieving 300°C vs. superalloys)
Emerging applications encompass 5G antenna radomes (low dielectric loss ceramics) and hydrogen energy (proton-conducting ceramics for electrolyzers). These materials are increasingly processed via additive manufacturing (DLP/SLS) to achieve complex geometries with ±25 µm dimensional accuracy.
