Introduction Carbon nanotube was the allotrope of carbon element and one-dimensional carbon material.
Experimental system and materials In general, there are three key components required for nanotube synthesis.
The burner consists of inside and outside two layers of casing (made up of type304 stainless steel material).
The dicyclopentadienyl iron was not suitable for synthesis of carbon nano-materials in the flame method.
Acknowledgments This research was supported by National Natural Science Foundation of China (NO.51106012).

Followed along with the progress of science and technology, people use visual experimental equipment to test the working process of the extrusion system, the extrusion process have a more intuitive understanding of the phenomena and issues.
Slotted cylinder with mandatory transmission performance, due to the friction between the material can produce a lot of heat.
Melt-segment design starting point is with the feed zone of high transmission capacity to match the material to fully melt, Ultimately, the pressure is low, mixed, high output extrusion material.

From both materials cement pastes of normal consistency were prepared according to the Czech standard ČSN EN 196 - 3 + A1 [10], see Table 1.
Values of compressive strength showed similar results although in smaller scale – the mutual differences in compressive strength between the two materials were not so significant.
