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.

You can combine search terms with and, or and/or not, e.g. Philo not logy.
You can use brackets to separate combinations from each other, e.g. (Philo not logy) or (Psycho and logy).
Coherent groups of words will be located as complete phrases if you put them into quotation marks, e.g. “Federal Republic of Germany”.
You can also use the advanced search without entering search terms. It will then follow the criteria you have selected (e.g. country or subject area).
If you have not selected any criteria in a given category, the entire category will be searched (e.g. all subject areas or all countries).
