The morphologies and purity of CNTs obtained at different temperatures in the range of 700℃-850℃ were investigated. At the optimal decomposition temperature 770℃ the pure product shows uniform diameter, small curvature and high yield. The more important thing is that there is no unremovable oxide support in the products, which represent the excellent properties of MCNTs.

球磨50h，形成了bcc结构的顺磁性纳米晶Cr-Fe-V合金。在富Cr的合金成份内，Fe含量越高，生成均质的纳米晶Fe-Cr-V合金所需的球磨时间越长。

SiC nanowires grew at the surface of liquid ball and formed villiform nano wire-balls. During the cooling stage in some cases, the SiO reacted with the CO in the furnace to form SiO_2 which then deposited on the surface of SiC nanowires, forming the SiC/SiO_2 nanocable with SiC as the core and SiO_2 as the wrapping layer.

由于Ni-Si化合物跟石墨的浸润性较差，在仅比化合物熔点高出小于200℃的温度区域内，Ni-Si化合物熔体不能在石墨板上熔敷而是形成合金熔球，最后在熔球表面上生长出SiC纳米线形成形状独特的SiC纳米线绒球。
