Preceramic polymers were proposed over 30 years ago as precursors for the fabrication of mainly Si-based advanced ceramics, generally denoted as polymer-derived ceramics (PDCs). The polymer to ceramic transformation process enabled significant technological breakthroughs in ceramic science and technology, such as the development of ceramic fibers, coatings or ceramics stable at ultra-high temperatures (up to 2000°C) with respect to decomposition, crystallization, phase separation and creep. In recent years, several important advances have been achieved such as the discovery of a variety of functional properties associated with PDCs. Consequently, possible fields of applications of PDCs have been significantly extended by the recent research & development activities. Several key engineering fields suitable for application of PDCs include high-temperature resistant materials (energy materials, automotive, aerospace, etc.), hard materials, chemical engineering (catalyst support, food- and biotechnology, etc.), or functional materials in electrical engineering as well as in micro/nano-electronics.
