2800℃ degree graphitization furnace for CNT/VGCF carbon nanotubes purification

Product Introduction

CNT can be single-, double-, and multi-walled. CNT have unique mechanical, electrical, and optical properties, all of which have been extensively studied. The novel properties of CNT are their light weight, small size with a high aspect ratio, good tensile strength, and good conducting characteristics, which make them useful for optics, electronics, sensing, mechanical, electrical, storage, and other fields of materials science are presented in the review.

 CXinduction® high temp graphitization furnace is ideal for powder type materials, like CNT carbon nanotubes heat process, VGCF vapor-grown carbon fiver purification, Max working temp to 2800C can greatly remove the impurities and defacts.

Vertical structure, top-loading type, Cylindrical chamer with higher heating efficiency. Further Carbon nanotubes grown by CVD with nano-catalyst particles need to remove the catalyst particles to obtain high-purity carbon nanotubes in practical applications. The high-temperature method by our furnaces, which can reduce the catalyst content in the carbon nanotubes to less than 5ppm. And obtain a higher degree of graphitization and purity.

 

Application:

Our Graphitization also suit for other advanced carbon materials, carbon fiber rope, carbon fiber, C/C composites, Graphene, battery anode materials, sintering of advanced ceramics and other materials which can be sintered in graphite hot zone (carbon included environment). 

We have both lab type and production type for you, welcome to send samples for testing!
