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

DC Katrin Schwarz Presse- und Öffentlichkeitsarbeit
Fraunhofer-Institut für Keramische Technologien und Systeme IKTS

    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.
