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.

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.

Technical ceramics, also known as engineered or advanced ceramics, are inorganic, non-metallic materials specifically designed for demanding industrial applications. These high-performance materials exhibit exceptional properties that surpass traditional ceramics in multiple aspects.

Special ceramics, also known as advanced ceramics, precision ceramics, technical ceramics, etc., refer to the use of high-purity, ultra-fine synthetic or selected inorganic compounds as raw materials, and have excellent mechanical, acoustic, optical, thermal, electrical and other properties. , biological and other characteristic ceramics.
Special ceramics are different from traditional ceramics in terms of raw materials and processes. The specific fine structure makes it have a series of advantages such as high strength, high hardness, wear resistance, corrosion resistance, high temperature resistance, insulation, superconductivity, biocompatibility, etc. It is widely used in national defense, chemical industry, metallurgy, electronics, machinery, aviation , aerospace, biomedicine, etc.

Engineering ceramics can be divided into oxide ceramics, nitride ceramics, carbide ceramics, boride ceramics, silicide ceramics, fluoride ceramics, and sulfide ceramics according to their chemical composition.
