Abstract
In order to study the properties of ultrafine 5 ,7-diamino-4 ,6-dinitrobenzenfuroxan (DADNBF) , ultrafine DADNBF was prepared using solvent/non-solvent method .The particle size distribution ,impact sensitivi-ty ,thermal stability ,vacuum stability ,shock sensitivity and flyer sensitivity of ultrafine DADNBF were compara-tively analyzed with raw DADNBF and ultrafine HNS-Ⅳ .The results show that the particle size distribution of ul-trafine DADNBF is in a range of 0 0.35-0 3.16 μm ,the specific surface area is 25 1. m2/g ,and the impact sensitivity (H50 ) is 108cm .The temperature at the exothermic peak of ultrafine DADNBF is 300℃ ,13℃ lower than that of the raw DADNBF .The critical initiation voltage of ultrafine DADNBF in flyer initiation test is 2 .35 kV and the shock sensitivity (X50 ) is 7 .54 mm .The comprehensive properties of ultrafine DADNBF are similar to ultrafine HNS-Ⅳ .关键词
