Abstract

The processes occurring during mixing two-component fuel–oxidizer powder mixtures in a ball-mill were explored by the methods of impedance spectroscopy. A transition from the ‘globular’ to ‘framed’ type of conductivity was found to happen after 15 hours of ball milling. Impedance spectroscopy can be used to determine (1) the moment of homogenization and (b) the onset of mechanochemical reaction in the course of intermixing.

用于SHS反应的绿色混合物的制备：阻抗谱表征

摘要

通过阻抗光谱法研究了在球磨机中混合两组分燃料-氧化剂粉末混合物时发生的过程。在球磨15小时后，发现发生了从“球形”到“框架”型导电性的转变。阻抗谱可用于确定（1）均质化的时刻和（b）混合过程中机械化学反应的开始。
