Abstract
Microstructure and reactivity (with a silicate matrix) of a new silicon nitride fibre were examined. The fibre was non-crystalline in as-received state and contained oxygen and carbon as impurities. Si-29 magic angle spinning nuclear magnetic resonance (MAS-NMR) study indicated the presence of SiN4, SiC4 and their mixed coordinations in the structure. Further, when these fibres are incorporated in a magnesium aluminosilicate matrix, a silica-rich reaction layer with small amount carbon precipitation has been observed at the fibre-matrix interface.
