摘要: Abstract Structurally similar silicone ceramers were synthesized by sol–gel processing of organic silanes. The chemical structures the hardened ceramer materials investigated studying gaseous products produced during elevated temperature heating. Fourier transformation infra-red (FTIR) spectroscopy and thermogravimetric analysis (TGA) utilized to study degradation phenomenon in ceramers. pyrolyzed residues analyzed Raman 29Si solid-state nuclear magnetic resonance (SSNMR) X-ray diffraction (XRD) techniques. surfaces with a scanning electron microscope (SEM). results from characterization techniques investigate mechanisms materials.
