The present application relates to boron nitride nanotube (BNNT)-silicate glass composites and to methods of preparing such composites. The methods comprise mixing BNNTs that are coated with a glass former such as boron oxide with a silicate glass precursor to create a mixture; heating the mixture under conditions to obtain a molten silicate glass; and cooling the molten silicate glass under conditions to obtain the BNNT-silicate glass composite.

Boron nitride nanotube-silicate glass composites

The present application relates to boron nitride nanotube (BNNT)-nanoparticle composites, to methods of preparing such composites and their use, for example, in metal/ceramic matrix composites and/or macroscopic assemblies. For example, the methods comprise subjecting a source of hydrogen, a source of boron, a source of nitrogen and a nanoparticle precursor to a stable induction thermal plasma and cooling the reaction mixture to obtain the composite.

Boron nitride nanotube (BNNT)-nanoparticle composites, methods for the preparation thereof and their macroscopic assemblies

Provided is a process and an apparatus for purifying boron nitride nanotube (BNNT) materials. The process involves the use of a halogen gas to remove halogen-reactive impurities from boron nitride nanotube (BNNT) materials in a single step with minimal interactions to produce structurally pristine BNNT. Gaseous byproducts are produced that 5 can be removed without the need for solution phase treatments. Yield efficiencies and purity of recovered BNNT are high compared to the other known methods of purification for BNNT material.

Process and apparatus for purifying BNNT

A composite includes a plastic substrate and an electrical insulator layer formed on the plastic substrate. The electrical insulator layer contains boron nitride nanotubes (BNNTs), which may be unmodified or modified BNNTS. The composite is suitable for use in making printed electronic devices. A process includes providing a plastic substrate and forming on at least a portion of a surface of the plastic substrate a layer that contains the BNNTs. A metallic ink trace is formed on a portion of the layer, such that the metallic ink trace is spaced-apart from the substrate. Using photonic or thermal sintering techniques, the metallic ink trace is then sintered.
