High Temperature Furnace Apparatus for Electrical Property Characterization of Ceramic Materials
Abstract
The National Defense Authorization Act for Fiscal Year (FY) 2016, under authority of 10 U.S.C. ¤ 2362 and the Office of the Assistant Secretary of Defense for Research and Engineering (OASD(R&E)), allocated $28 million to assist Historically Black Colleges and Universities and Minority-Serving Institutions (HBCU/MI) with equipment and instrumentation enhancements to improve their research and education capabilities in scientific disciplines important to the defense mission. The program aims enhance the capacity of HBCU/MI to participate broadly in defense research programs and activities and to increase the number of graduates, including underrepresented minorities, in fields of science, technology, engineering, and mathematics (STEM). This proposal seeks to create a platform to measure the electrical properties of ceramic materials at high temperature (up to 3000oC) to enhance our current ONR-funded Young InvestigatorProgram (YIP) (ÒMultifunctional Ceramic Nanocomposites Reinforced With A High Volume Fraction of Well-Dispersed and Aligned Carbon NanotubesÓ, #N00014-14-1-0543) and the new proposed topic on ÒHybrid Multifunctional Layer Materials by Co-curing Lay-up Process for Enhanced Thermal/Electrical Exposure and Surface DurabilityÓ. The PI plans to establish a high temperature furnace apparatus to characterize the temperature-dependent and composition-dependent electrical properties of ceramic materials at very high temperature. Two experimental setups will be designed: (1) the first will measure DC electrical resistivity using the four-point probe method; and (2) the second will measure the dielectric properties of ceramic materials using free space measurement. The characterization of ceramicÕs electrical properties under very high temperature has become critically important to understanding and improving its functional applications in extreme conditions. However, there is very limited setup for high temperature electrical property measurement to high temperature. Existing research in this area extends to temperatures of only 1000oC, which is quite limited for actual applications. The proposed furnace will advance the capability and efficiency of the fabrication facilities and will enable the PIÕs team to perform characterization for high temperature ceramic materials. This enrichment of our facultyÕs capabilities will be highly beneficial to ONR and many other Department of Defense (DoD) units, as well as supporting research for NSF and other agencies. Acquisition of this equipment will be vital to extending the scope of current projects and developing new projects. It will provide a solid foundation for the PI and others to continuously develop research that relates to the defense mission and the challenges in science and engineering today.
