Abstract:
1. A method of producing MgB 2 boron nitride nanotubes, the method comprising: (a) providing an integrated production apparatus, the apparatus comprising: a pressurized reaction chamber containing a continuously fed boron-magnesium containing target having a boron and magnesium target tip, a source of pressurized nitrogen and a moving belt condenser apparatus including a belt surface; a target feed system wherein the target feed system provides a continuously fed boron and magnesium containing target to the pressurized reaction chamber; a nitrogen control system in communication with the pressurized nitrogen; and a laser beam and optics wherein the optics direct the laser beam though a laser beam tube and into the pressurized reaction chamber; (b) providing nitrogen gas to the pressurized reaction chamber to maintain a pressure of about 50 to 1000 psi in the pressurized reaction chamber; (c) providing a laser beam and maintaining a laser power within the range of 100 to 25,000 W; (d) directing the laser beam to the tip of the boron-magnesium target; and (e) collecting MgB
