Stacking faults in silicon carbide whiskers

A significant challenge in synthesizing nanowire/nanobelt-reinforced ceramic nanocomposites is to uniformly disperse these reinforcements. Here, we report the synthesis of amorphous silicon carbonitride powders containing in situ-formed single-crystal Si3N4 nanowires and nanobelts via the catalyst-assisted pyrolysis of a polymeric precursor. The nanowires/nanobelts are uniformly dispersed within the powder matrix. The ratio of nanomaterials to powder can be controlled by tailoring the experimental conditions. The novel powders could be useful for fabricating nanowire/nanobelt-reinforced ceramic nanocomposites.

Structural development and properties of SiC-Si3N4 nano/microcomposites

We synthesized silicon carbide (β-SiC) nanowires with nano-scale diameter (30 400 nm) and micro-scale length (50 200 μm) on a porous body using low-grade silica and carbon black powder by carbothermal reduction at 1300 1600oC. The SiC nanowires were formed by vapor-liquid-solid deposition with self-evaporated Fe catalysts in low-grade silica. We investigated the characteristics of the SiC nanowires, which were grown on a porous body with Ar flowing in a vacuum furnace. Their structural, optical, and electrical properties were analyzed with X-ray diffraction (XRD), transmission electron microscopy (TEM), and selective area electron diffraction (SAED). We obtained high-quality SiC single crystalline nanowire without stacking faults that may have uses in industrial applications.

Growth of SiC-AlN whisker with the polytype of 2H

A detailed microstructural analysis of slip-cast Si3N4/SiC-whisker composites has been made by TEM. In spite of the gentle forming process, SiC whisker breakage constitutes a fundamental feature of this material. The breaking takes place during the sintering process and could be associated with residual thermal stresses, as revealed by the experimental evidence. The dramatic decrease in the whiskers aspect ratio translates into little or no effect of whisker addition on the mechanical properties of the Si3N4 matrix.
