Abstract:

This work describes the obtaining of silicon nitride, a ceramic powder for advanced ceramics, starting from mesoporous silica, which is obtained by acidic attack of serpentinite rocks. Serpentinite rocks come from the heaps resulted from the former exploitation of asbestos in the South West of Romania.
The mesoporous silica was used as a host for the polymerization of acrylonitrile in order to obtain hybrid inorganic-organic polymer nanocomposites. The hybrid nanocomposites were turned into silicon nitride by 3 subsequent thermal treatments in controlled atmosphere.
The chemical and structural changes during the preparation process of Si3N4 starting from serpentinite were followed by FTIR, BET, XPS, GPC, SEM, TEM, XRD, TGA-DTG and by chemical analytical methods.

Keywords:

Ceramic, silicon nitride, polymer, hybrid, nanocomposite
