摘要
PROBLEM TO BE SOLVED: To provide a boron nitride nanofiber having a long-period structure and useful as a material for microelectronic parts, high-performance ceramics, a material for optoelectronic parts, catalysts, etc., and provide a method for producing the same.;SOLUTION: Carbon nanotubes are deposited on a titanium substrate containing dispersed fine cobalt particles by plasma CVD process using a mixture of methane gas and hydrogen gas and keeping the substrate temperature at 500°C and the substrate holding the deposited carbon nanotubes is subjected to substitution reaction with boron oxide in nitrogen stream at 1500-2000°C to obtain the boron nitride nanofibers having a long-period structure consisting of 12-layer period and 24-layer period.;COPYRIGHT: (C)2004,JPO&NCIPI
