Synthesis and characterization of ropes made of BN multiwalled nanotubes

Nanotubes are considered to be unique structural and electronic materials. The possibility of boron nitride nanotubes as a nanoinsulating shield for any conducting material is also considered. Multiwalled boron nitride nanotubes were synthesized under heating of chemically-vapor-deposited multiwalled carbon nanotubes and boron trioxide to 1773 K over 30-60 minutes by induction currents in a flowing nitrogen atmosphere. An HRTEM micrograph of a representative rope synthesized using a PbO-promoter was described.
