#0183;#32;In this work, a novel methodology to dope carbon nanotubes with nitrogen by ball milling is proposed. This simple method of obtaining NCNT can be easily scaled up. In this process, the preparation method is simple and reduces significantly the
BALL MILLING Ball milling is a method of production of nano materials. This process is used in producing metallic and ceramic nano materials. These mills are equipped with grinding media composed of wolfram carbide or steel. Ball mills rotate around a horizontal axis,partially filled with the material to be ground plus the grinding medium.
Ballmilling and annealing is one effective method for the mass production of boron nitride nanotubes (BNNTs). We report that the method has been modied to a boron (B) ink annealing method. In this new process, the nanosize ballmilled B particles are mixed with metal nitrate in
method, graphite powders in the elemental form were rstly exposed to milling process in highenergy ball milling and then the milled powders were annealed at high temperatures. As a result of milling of the graphite, ultraactive disordered carbon structures were obtained. This structure serves as a carbon source for the formation of nanotubes

Formation Of Nanotubes Ball Milling Method. Carbon nanotubes history and production methods is a guide to the various types of carbon nanotubes, purification and functionalization milling and subsequent annealing is a simple method for the production of disadvantage of this method is that some amount of nanotubes are inevitably lost in the.
It is demonstrated that unique carbon nanostructures including carbon nanotubes and carbon onions are synthesized by highspeed ballmilling of steel balls. It is considered that the gasphase reaction takes place around the surface of steel balls under local high temperatures induced by the collisionfriction energy in ballmilling process, which results in phase separated unique carbon nanomaterials.
#0183;#32;In addition, unlike other synthesis methods, the ball millingannealing method has a solidstate formation process without the involvement of any vapor phase, and this has significant interest in understanding fundamental formation mechanisms. The ball millingannealing method can produce other nanotubes such as boron nitride (BN) nanotubes .
Mechanothermal method was used for synthesizing the carbon nanotubes (CNTs) in this study. In this method, graphite powders in the elemental form were firstly exposed to milling process in highenergy ball milling and then the milled powders were annealed at high temperatures. As a result of milling of the graphite, ultraactive disordered carbon structures were obtained.
Highyield multiwalled boron nitride (BN) nanotubes have been produced using a ball millingannealing method. The BN nanotubes with a diameter less than 10 nm and a wellcrystallized multiwalled structure were formed via an in situ nitriding reaction. The systematic investigation of the formation process at different annealing temperatures and for different times suggested that the formation

#0183;#32;Abstract. Ndoped carbon materials are promising metalfree catalysts for a number of applications. In this work, a cost effective and easy method to prepare Ndoped carbon nanotubes by ball milling was developed, which avoids the use of solvents and production of wastes. Melamine and urea were used as nitrogen precursors.
