Abstract Scope |
Preceramic polymers were proposed more than 40 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. Preceramic polymers have been used as reactive binders to produce technical ceramics, they have been manipulated to allow for the formation of ordered pores in the meso-range, they have been tested for joining advanced ceramic components and have been processed into bulk or macro-porous components. In the present presentation, the focus is another developing field of preceramic polymers, namely their high potential in additive manufacturing technologies which allows for the fabrication of high-temperature resistant advanced ceramics and ceramic (nano)composites with complex geometries and shapes. |
