Cryomilling, also known as cryogenic milling or cold grinding, is a process of reducing the size of materials using liquid nitrogen or other cryogenic gases. This technique is widely used in various fields of research, including materials science, chemical engineering, and pharmaceuticals. Synonyms for cryomilling include cryogrinding, cryocutting, cryopulverization, cryocomminution, cryofracture, and cryotransformation. All of these terms represent the same process of reducing the particle size of materials through low-temperature grinding. Cryomilling offers advantages such as improved particle size distribution, reduced thermal degradation, and enhanced chemical stability of the resulting product. It is a highly efficient and versatile method for a wide range of applications.
