Polymer-derived ceramics

The formation of ceramic materials via the polymer route (polymer-derived ceramics) is an alternative to the conventional ceramic processing involving powders. Starting with a pre-ceramic polymer compound (primarily Si-based, e.g. polysiloxanes, polysilazanes,...), a controlled thermal decomposition yields amorphous or crystalline ceramic materials.

Advantages of the polymer route include:

  • novel approaches to obtain bulk, cellular, or layered ceramic materials due to the polymeric nature of preceramic compounds,
  • significantly reduced process temperatures,
  • high green strengths resulting in improved machinability in green/polymer state, as well as
  • the possibility to yield novel ceramic compounds.

Our group exploits all of the advantages mentioned in order to develop advanced materials for continuously increasing structural, chemical, and thermal demands in a wide variety of potential application fields, including sustainability- and energy-related applications. 

 

We focus on the use of preceramic polymers for the generation of

porous and cellular ceramics with finely tuned pore structures, with tailored pore dimensions ranging from the nm- to the mm-range,

bulk ceramics with controlled shrinkage and beneficial machinability in green state, and

functional non-oxide ceramic coatings.
