Summary

The objective of this project was to create unique composites using microwave induced reduction and oxidation reactions and analyze the resulting properties. Ceramic-metal composites (CMC) were formed by reducing ceramic oxides and oxidizing metal powders. Ceramic and metal powders were pressed into discs and processed in a highly reducing atmosphere using microwave hybrid heating. Two systems were studied: CuO/Al and MgTiO3. The reduction/oxidation (redox) of the CuO/Al resulted in a Cu/Al2O3 composite. Reduction of the MgTiO3 created a conductive MgTiO3-x composite. Multilayered composites were created by alternating layers of the conductive MgTiO3-x and the dielectric MgTiO3.
