Synthesis and growth of boron nitride nanotubes by a ball milling–annealing process. The synthesis and growth of boron nitride nanotubes (BNNTs) based on ball milling of crystalline boron powder followed by heat treatment were investigated. Fe-based stainless steel (STS) balls and milling vessels were used for milling, and the Fe impurity ...
