The spheroidization of energetic materials can significantly improve the processing and application properties of explosive crystals. Based on the current research on spheroidization technology of typical energetic materials both in China and abroad， the research progress of spherical single crystals， spherical agglomerates and spherical branched crystals are reviewed from the perspective of crystallization strategy. The crystallization process， spheroidization mechanism and desensitization effect of spherical products are emphatically introduced. It is showed that spherical products have the virtues of good flowability， high bulk density and low sensitivity， and have great potential in explosive applications. Combining crystal engineering thinking， it is suggested to construct the crystallization database of typical energetic materials， strengthen online process monitoring， improve model calculations and multidisciplinary cross study， thus providing guidance for precise regulation and industrial production of spherical crystallization process of energetic materials.
