The peculiarities of transformation of organosilicon polymer into ceramic products under mechanochemical treatment

The effect of mechanical treatment on polygermasilethyne for different periods of time was studied. The structural and chemical transformations of polygermasilethyne into ceramic products induced during a high-energy ball milling were investigated by infrared and Raman spectroscopy, thermal analysis, X-ray analysis, as well as scanning electron microscopy analysis with using EDS spectrometer. It was shown that high-energy mechanical treatment leads to the cross-linking process including the formation of new covalent bonds between molecules and rigid three-dimensional network. Simultaneously an amorphous solid network is converted to nano- and microsized inorganic phases, namely, silicon carbide, carbon and germanium-containing phase.
