This book collects some of papers presented at the very successful Symposium "Polymer Derived Ceramics and Composites" in the framework of the 8th Pacific Rim Conference on Ceramic and Glass Technology. There, over 70 researchers from around the world discussed their latest innovations over four full days. It covers all the main aspects of interdisciplinary research and development in the field of Polymer-Derived-Ceramics, from the precursor synthesis and characteristics to the polymer-to-ceramic conversion, from processing and shaping of preceramic polymers into ceramic components to their microstructure at the nano- and micro-scale, from their properties to their most relevant applications in different fields.
