| Abstract: | Si-B-O-N ceramic powders with specific structural characteristics and free boron oxide were designed at molecular level. Organo-polymeric precursors prepared by sol-gel method are used to produce ceramic powders through pyrolysis. The chemical features and morphologies of the produced powders were investigated by means of XRD, FT-IR, and TEM. Experimental results show that Si-B-O-N ceramic powders are amorphous state, composed of B-N loops, Si-O and Si-N-O groups. The morphologies of the powders are even spherical particles about 50 nm in diameter. |
