NTO结晶及改性技术研究进展
Research Progress of NTO Crystallization and Modification Technology
摘要
Abstract
3-Nitro-1,2,4-triazole-5-one(NTO)is a typical insensitive energetic material that combines low sensitivity,high ener-gy density,and a simple manufacturing process.In recent years,it has attracted significant attention from researchers.The crys-tallization characteristics of NTO,including crystal morphology and particle size,are critical factors in its production and appli-cation,directly influencing its flowability,bulk density,formulation safety,and detonation performance.This study presents a systematic review of recent advancements in NTO crystallization and modification technologies,covering aspects such as crystal-lization fundamentals,particle size and morphology control,cocrystal formation,and coating techniques.Particular emphasis is placed on the thermodynamic and kinetic properties of NTO crystallization in commonly used solvents,as well as the applica-tion of spherulization techniques.Furthermore,the study highlights effective strategies for simultaneously enhancing both energy performance and safety through cocrystal and coating approaches.It is recommended that future research efforts further explore or strengthen green crystallization techniques based on aqueous systems,the preparation of spherical single crystals,crystallizer design,and flow field simulations.These advancements will facilitate precise control of crystallization processes in industrial pro-duction and accelerate the development of multi-specification NTO crystal products tailored to various application scenarios.关键词
