Abstract: The present paper reviews preparation principles, features, applications, existing problems and development trends of several important preparation methods of spherical micro particles, such as cutting, punching-remelting method, atomization, uniform-droplet spray method (UDS) and pulsated orifice ejection method (POEM). In addition, solidification behavior of droplets is particularly pointed out. In summary, POEM is a promising practical method with characteristics of identical size, high sphericity, particle size controllable and the same cooling history, especially in preparing function particles and high melting point materials.
