The Effect of Annealing Time on the Synthesis of Boron Nitride Nano Tubes by High Energy Ball Grinding and Annealing Method
Journal Title: Gazi Üniversitesi Fen Bilimleri Dergisi Part C: Tasarım ve Teknoloji - Year 2013, Vol 1, Issue 1
Abstract
In this study, Boron Nitride Nanotubes (BNNTs) were synthesized using a ball-milling and annealing method. Starting powder was used as the amorphous boron powder and in a planetary ball mill (FritschPulverisette 7 Premium Line) was ball milled for 2 hours under nitrogen atmosphere. After milling process, obtained powders were annealed under NH3+N2 flow at 1300ᴼC for different time as 2,4,6 hrs in tube furnace. Consequently, the boron nitride nanotubes were produced by using this technique. Synthesized tubes were determined by using X-ray diffraction analysis (XRD), high-resolution transmission electron microscopy (HR-TEM)
