  • PROCESS AND APPARATUS FOR PURIFYING BNNT
    Publication number: 20210261414
    Abstract: 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.
