摘要
硝酸铵是一种多晶型的物质 ,受外界因素影响易结块。该文通过添加无机盐对硝酸铵进行作用 ,并运用热分析方法及材料实验方法 ,针对 10余种无机盐添加剂作用后对硝酸铵的晶变影响及抗压强度进行了实验研究。结果表明 ,几种添加剂对硝酸铵的晶变和抗结块性能有一定的改善 ,无机盐影响硝酸铵晶变和结块性的原因主要是结晶方式、离子半径、电荷数。
Ammonium nitrate (AN) is a kind of polymorphous substance which is subjected to caking due to environmental factors.With the DSC and compressing test method,effect of more than 10 kinds of inorganic salt on AN polymorphism and caking property is discussed.Results show that some of these additives have good performance,which was mainly caused by the multiple effects of co crystallization type,ionic radius,charges,ion stereo structure and so on.
