Effects of Zr on the precursor architecture and high-temperature nanostructure evolution of SiOC polymer-derived ceramics

Effects of Zr on the precursor architecture and high-temperature nanostructure evolution of SiOC polymer-derived ceramics ژورنال: Journal of the European Ceramic Society سال: October 2015 قیمت اصلی: 35.95$   AbstractSiOC and SiZrOC ceramics were obtained starting from the hydrosilane system without and with zirconium n-propoxide (Zr(OnPr)4) by sol–gel route. The precursor architectures indicated that the presence of SiH bonds leads to a different cross-linking mechanism of SiZr ...
