Influence of jet milling process parameters on particle

Jet milling pressure plays a critical role in controlling the decomposition of MnBi. • As the jet pressure increases, more amount of MnBi phase decomposes. • Moderate milling pressure has resulted in powders with good properties. • Jet milled powders displayed high coercivity (H c) values of about 18 kOe.
