The role of ultrasound in the nucleation kinetics and Modification of product properties of 3-Nitro-1,2,4-triazol-5-one.

ABSTRACT: 3-Nitro-1,2,4-triazol-5-one (NTO), a well-known energetic material, is extensively employed in the field of insensitive munitions. However, its irregular crystal morphology and broad particle-size distribution hinder its wider application. Ultrasonic-assisted crystallization offers an innovative approach to enhance the overall particle performance of NTO. In this study, NTO was subjected to ultrasound-assisted cooling crystallization using water as the solvent to control the crystal size and morphology, as well as remove adhered nitric acid and ensure environmentally production. The metastable zone width (MSZW) of NTO in aqueous solution was subsequently measured to understand the nucleation kinetics, revealing a significant reduction under ultrasonic irradiation. Employing Sangwal's three
