Title:

MANUFACTURING METHOD OF BORON NITRIDE NANOTUBE

Document Type and Number:

Japanese Patent JP3834640

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To easily synthesize a large amount of a boron nitride nanotube which does not contain impurities, such as carbon, and is suitable for practical use.
SOLUTION: Boron is thermally reacted with a reactive gas comprising at least either a nitrogen gas or an ammonia gas in the presence of a catalyst comprising nickel boride carried by alumina.
