文摘

Multiwall boron nitride nanotubes (BNNTs) were produced with a yield of about 50% byco-pyrolyzing NH₄BF₄, KBH₄, and NaN₃ in a temperature range from 450 to 600 C. Theobtained BNNTs have a diameter range of 60-350 nm and length range of 0.5-5 m. ManyBN nanocages were found coexisting with the BNNTs. The experimental results indicatedthat NH₄BF₄ plays a crucial role in the formation of BN nanotubes. The effects of otherreactants were also investigated.
