Ball Milling - an overview | ScienceDirect Topics
It is proposed that BN nanoparticles formed during the milling process act as nucleation sites for growth during annealing process. Apart from them, contaminant Fe nanoparticles introduced during the milling process also served as catalyst for the growth. However, the quality and purity of BNNTs grown by ball milling was not satisfactory.
