5.2 Pyrolysis of Active and Passive Filler-loaded Preceramic Polymers

摘要: This chapter discusses the fundamental aspects of filler to polymer interaction during manufacturing ceramics from filler-loaded preceramic polymers. Both active as well inert fillers may be used reduce overall dimensional changes associated with thermal degradation phase. Additionally, have a strong impact on resulting properties such mechanical, electrical, and behavior. Incorporation offers possibility improve mechanical physical chemical polymer-derived ceramics. Preceramic polymers containing can transformed ceramic microcomposites reduced shrinkage pyrolysis. Volume-invariant polymer-ceramic conversion is attributed reaction reactive solid or gaseous decomposition products in formation network Reduction pyrolysis temperature results partially converted organic-inorganic hybrid materials. Compared high-temperature polymers, novel materials an improved stability, whereas, compared conventional ceramics, they offer better geometrical accuracy at significantly lower temperatures. Tailoring hierarchical microstructures new possibilities for application fields machinery, electronics, medicine.
