为了拓展2,6-二氨基-3,5-二硝基-吡嗪-1-氧(ANPZO)炸药的应用范围,采用重结晶和气动喷雾细化方法制备了立方体状、棒状和超细化球形三种ANPZO晶体,对其冲击波感度、机械感度、热性能和爆速进行了测试研究,结果表明:结晶形状对ANPZO冲击波感度影响较小,配方ANPZO/粘结剂=97.5/2.5的50％起爆隔板值约为3.65 mm,晶形对ANPZO的机械感度影响较大,棒状晶体最敏感.ANPZO热性能稳定,最大放热峰值可达350℃以上,5 s延滞期爆发点为302℃,配方ANPZO/粘结剂=96.5/3.5慢速烤燃试验中试样在305℃下分解,未爆轰.立方体晶形配方ANPZO/粘结剂=96.5/3.5的压药密度为1.855 g·cm-3时,爆速可达8070 m·s-1.%In order to extend the application of 2 ,6-diamino-3 ,5-dinitropyrazine-1-oxide (ANPZO), three different ANPZO crystallines with cubic, needle and ultrafine shape were obtained by recrystallization and pneumatic spray refining. Some sensitivities and performance of ANPZO explosive were characterized, such as shock wave sensitivity, mechanical sensitivity, thermal behavior and detonation velocity. Results show that the shock wave sensitivities for different ANPZO crystal shapes are nearly the same with approximate 3. 65mm in D50. The mechanical sensitivity of cubic ANPZO crystal is lower than that of other crystals. ANPZO is thermally stable with maximum heat release peak value of 350℃ , the 5 s delay explosion temperature as 302℃ and the decomposition temperature as 305 XL in slow cook-off test. Detonation velocity measured is up to 8070 m·s-1 with the density of 1. 855. g·cm-3.
