PRODUCTION METHOD FOR BORON NITRIDE NANOTUBE

摘要

PROBLEM TO BE SOLVED: To provide a method for mass-producing a high-purity boron nitride nanotube not containing an impurity such as carbon. SOLUTION: A mixture of boron and magnesium oxide in equimolar amounts is heated at 1,500°C while an inert gas is being introduced upward from below into a reaction chamber and an ammonia gas, downward from above into the chamber, respectively.
