The objective this AFOSR sponsored project was to design, synthesize and explore the materials applications of new, processable single-source chemical precursors to nonoxide ceramics that allow the formation of these technologically important materials in forms that have been unattainable with conventional methods. Research was focused on the development of new precursor routes to a number of ultra high temperature ceramics, including hafnium and zirconium -boride, -carbide and -nitride materials, and on the use of electrostatic spinning and diatom-templating methods, in conjunction with newly designed preceramic polymers, to achieve the formation of nano-structured ceramic materials.
