STUDY ON FINING TECHNIQUE OF HNS

摘要

The preparation technology of ultrafine HNS by recrystallization method was presented. The high-dispersed explosive solution was splashed into low-temperature water and the fitting surfactant was added at the same time. The specific surface area of ultrafine HNS particle was up to 23.00m~2/g (square meter per gram). Mean diameter of HNS particles was 0.365μm (micron). Sample purity was over 98.5% .
