BNNT Products

NanoBorNT(means 쏝orn to Nano)
NanoBorNT is a trademark for Naieel Technology셲 BNNT product.
High quality BNNT products are currently available with 80 wt% purity (NanoBorNT-80) and 90 wt% (NanoBorNT-90) purity, respectively. Naieel Technology셲 BNNT products are world renowned in their superior quality as well as industrial applications in addition to the cheapest prices among others.
NanoBorNT-80 (>80wt%)
NanoBorNT-80 is a Naieel Technology's industrial grade BNNT product. NanoBorNT-80 can be used in various academic as well as industrial R&Ds in addition to the applications for the industrial products.
NanoBorNT-80 powder contains 80% of BNNT in weight, while the balance is h-BN with the trace of metallic impurity. NanoBorNT-80 can be used virtually in every industry for IT/IoT, energy and environment, space and nuclear, and even biomedical applications Currently, Naieel Technology can offer kg셲 even ton셲 of NanoBorNT-80 (please contact us for the industrial supply).

Structure of BNNT

Fundamental crystallographic structure of BNNT is same with CNT, hexagonal planar layered hollow nanotube, except for the constituting atoms. Naieel Technology셲 BNNT is cylinder typed multi-walled with the outer diameter of 30~50 nm in average, and the length with 10 um in average. The ends of most BNNT are opened without nodes inside. Based on Raman spectrum, it is assumed that most BNNT are armchair structured while some are zigzag structured (Please contact us for more information for Raman property of our BNNT).
  • Zigzag
  • Amchair
  • Chiral

There are three structures of BNNT.(amchair, zigzag, chiral)
