Outstanding chemical, thermal and tribological properties predestine silicon carbide for the production of ceramic components of high volume. A novel method now overcomes the procedural and technical limitations of conventional design methods for the production of components with large differences in wall thickness and demanding undercuts.
Extremely hard as diamond, shrinking-free manufacturing, resistance to chemicals, wear and temperatures up to 1300 °C: Silicon carbide (SiSiC) bundles all these characteristics and is the key to competitive advantage in machinery and plant engineering.
Mineral casting principle in ceramic manufacturing expands opportunities
Scientists at Fraunhofer IKTS in Dresden have now developed a method by which the shaping of the material SiSiC for complex components can be realized cost-efficiently.
They adapted the proven production process for SiSiC-filled reaction resin concretes by SICcast Mineralguss GmbH to the ceramic manufacturing. A mixture of coarse particles with a polymeric binder is casted without pressure in open molds and subsequently tempered.
A method principle, which enables the production of large and complex components in one single step.
Increase of service life and productivity, minimization of costs
By the new method costly materials-, machinery- and personnel consuming module construction methods and combinations thereof are bypassed.
The economic process substitutes conventional materials such as metals or plastics in chemical and plant engineering, e.g. in the pump industry. With the allround material silicon carbide service life of machines can be increased by up to 100 %.
Further potential applications of the material are components of nozzles, mills or burners as well as structural components for high-precision applications in optical industry.
From April 13 to 17 you will meet IKTS scientists in Hall 6 on Booth B16.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
