129620A High Temperature Test System

• Room temperature to 1200ºC
• For testing solid oxide, solid electrolyte, super ionic conductors
• Dual gas design for SOFC.
• Split tube furnace for easy sample load

Impedance Spectroscopy measurements combine with sample holders and High Temperature Test Systems, such as furnaces, and Low Temperature Test Systems, such as cryostats, in order to characterize conductivity as a function of temperature.

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
