Nonoxide ceramics open up new perspectives for the chemical and plant engineering

01.04.2015

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.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...

Im Focus: Wrinkles give heat a jolt in pillared graphene

Rice University researchers test 3-D carbon nanostructures' thermal transport abilities

Pillared graphene would transfer heat better if the theoretical material had a few asymmetric junctions that caused wrinkles, according to Rice University...
