Abstract

Siliconboronoxycarbide (SiBOC) foams were prepared from borosiloxane precursors by sacrificial pu foam template method. Methyl borosiloxane oligomer was synthesized from boric acid and methyltriethoxysilane. This SiBOC precursor (methylborosiloxane) was pyrolyzed at 1000 degrees C in argon with a ceramic yield of amorphous SiBOC of similar to 78%. Compressive strength of the foam sample achieved values of 410kPa at a total porosity of 85% and a mean pore cell diameter of approx. 700 mu p.. Annealing at 1400 degrees C in argon resulted in beta-SiC crystallization and a SiC/SiBOC nano composite foam was formed.
