英文摘要：

Electrostatic levitation is an important technique for containerless processing. It can provide a clean and quiescent environment for superheating and supercooling in different materials, while real - time fusion and solidification processes can be detected by non -contact instruments around the levitated sample. The mechanism and applications of electrostatic levitation in materials science are reviewed, and future prospects discussed.
