Boron Nitride Nanotubes: Properties, Synthesis and

Synthesis of Born Nitride Nanotubes. BNNTs were first synthesized in 1995 by the arc discharge method. 2 Since then, other processes such as laser ablation, chemical vapor deposition, ball milling-annealing, pyrolysis and arc-jet plasma have been explored for the synthesis of BNNTs. In recent decades, inductively coupled plasma (ICP) technology has been used for the
