Boron Nitride Nanotubes: Multi-Walled Powder

BNNT-MW Powder




BNNT presents similar thermal conducting and mechanical properties compared to CNT, while its thermal/chemical stabilities, biocompatibility, electric insulating, and thermal neutron absorbing properties are much higher than those of CNT. Due to these superior properties, BNNT is currently under exploration in many areas of IT, space/nuclear, bio-medical, and energy.

Molecular Cross-Sectional Area 0.1620 nm
Diameter 50-100 nm

Product Applications


The primary usage for BNNT is to have the material serve as a Thermal Conductor. The thermal conductivity of a material can be multiplied by the incorporation of BNNT within composite materials.  Along with this, BNNT-MWs can also provide Electrical Insulation to materials utilized for information technology devices.

Electrical Insulating Thermal Conducting Material for IT Devices

In a Thermal Conductivity Comparison of 50wt% h-BN dispersed epoxy composite and 0.5wt% BNNT/49.5 wt% h-BN dispersed epoxy composite, Thermal conductivity (1.3 W/mK) was be enhanced as much as 3 times (3.4 W/mK) with only 0.5 wt% BNNT-MW (0.5 wt%). Additionally, this material at a BNNT density of 2.0 g/cm3 could provide a thermal conductivity of 10 W/mK. Furthermore, the Electric Breakdown Voltage for these prepared composites was 26.3 kV/mm.
