By the combination of experimental results with theory of crystal growth, some growth models and growth mechanisms were proposed. Research results confirmed that pillar-shaped TaC whisker with spherical droplet at the end grew via a vapor-liquid-solid mechanism, pillar-shaped whisker with pyramid-like end was formed via a vapor-solid mechanism, awl-shaped TaC whisker with zigzag end formed via a liquid-solid mechanism, awl-shaped TaC whisker with growth step at the end has a growth mechanism of screw dislocation mechanism. The growth mechanism of dumbbell-shaped MgO nanowhisker and NaCl particle-decorated MgO nanowhisker is VS; C and MgO powder-yielded MgO nanowhisker was formed via a VLS mechanism, Mg powder-yielded MgO microwhisker and MgO microsized or nanosized crystal sheet grew via a VS mechanism. In the Si and SiO〓 nanostructures, Si nanowires formed in higher-temperature zone grew via oxide-assistant mechanism, while Si nanowires or nanorods formed in lower-temperature zone have a growth mechanism of VLS, and the growth mechanism of SiO〓 nanowires is VS.
