摘要:
硝酸铵（AN）中添加质量分数5%的无机盐并碾磨混合，通过微热量热计研究4种常用无机盐对AN晶型Ⅳ~Ⅰ型转变的影响。结果表明：两种氯盐使AN晶型Ⅱ~Ⅰ型开始转变的温度明显提前；4种无机盐使AN晶型Ⅳ~Ⅲ型转化温度降低；硝酸钾使AN晶型Ⅲ~Ⅱ型转变温度提高约7 ℃，氯化钾提高约3 ℃；氯化钾可以使AN晶型的Ⅳ~Ⅲ型、Ⅲ~Ⅱ型相转变焓降低，使晶型转变难度增大；氯化钠使AN晶型转变焓明显增大，促进AN晶型转变。
Abstract:
5%（mass fraction） inorganic salt was added into ammonium nitrate (AN) and mixed under grinding. Effect of four common inorganic salts on the crystal transition (Ⅳ-Ⅰ) of AN was studied by micro calorimeter. The results show that transition temperature of Ⅱ-Ⅰ is obviously advanced by adding two kinds of chloride salts; transition temperature of Ⅳ-Ⅲ is reduced by addition of four inorganic salts. Transition temperature has been raised by about 7 ℃ by KNO3, and by about 3 ℃ by KCl. Phase transition enthalpy in conversion of crystal type Ⅳ-Ⅲ and Ⅲ-Ⅱ could be reduced by addition of KCl, and it can increase the difficulty of crystal transition. Enthalpy of AN crystal transition increases and transformation of AN crystal is facilitated by NaCl.
