Boron Nitride Nanotubes Market Overview

Boron Nitride Nanotubes (BNNTs) are cylindrical nanostructures composed of boron and nitrogen atoms arranged in a hexagonal lattice. Structurally similar to carbon nanotubes (CNTs), BNNTs offer distinct advantages such as high-temperature stability (>900°C in air), electrical insulation, and neutron absorption capability due to boron-10 isotope presence.BNNTs are increasingly being explored for use in ultra-strong, lightweight composites for aerospace structures, radiation shielding in space environments, drug delivery vectors in nanomedicine, and as thermally conductive fillers in electronics. Their non-reactive and piezoelectric nature also makes them ideal for use in harsh chemical or vacuum environments where conventional materials fail.Despite their promising attributes, BNNTs are still considered an emerging material due to limited large-scale production and application challenges. However, as synthesis technologies mature and integration techniques improve, BNNTs are expected to play a transformative role in the materials science and advanced nanotechnology sectors.
