| Ceramic materials generally vary in electrical and dielectric properties at elevated temperatures. However, there are very limited setups for high temperature electrical property measurement spanning from room temperature to extreme high temperature (up to 2500°C). We have been funded by a Department of Defense (DoD) DURIP project “High temperature furnace apparatus for electrical/dielectric property characterization of ceramic materials” to characterize the electrical/dielectric properties of ceramic materials at very high temperature, specifically the materials’ temperature-dependent and composition-dependent properties. With such equipment, we will be able to fabricate and characterize high temperature ceramic composites for both electromagnetic (EM) shielding and radiofrequency (RF) communication applications in oxidizing and extreme temperature environments. Additional benefits of this research can help identifying suitable materials/designs for oxidation resistant conformal high temperature RF antennas, which is of great importance to the electronics and defense industries. |
