  • Applications and Software +


    The flexible solution for materials characterization...
    The system uses a split tube furnace design together with a lab jack that allows easy sample access and positioning. The sample is positioned in a purpose designed sample holder between platinum electrodes that allow testing at very high temperature. Gases may also be applied to either side of the sample for solid oxide applications.

    Applications include:

    • Development of solid state, solid oxide, superionic, electro-ceramic materials
    • Energy applications include SOFC fuel cell and solid state battery
    • Aerospace/automotive applications – high temperature insulators, brakes, turbine blades
