摘要
The reactivity of aluminum powders is determined using the following parameters: the temperature of the onset of oxidation, maximum oxidation rate, degree of conversion (degree of oxidation) of aluminum, reduced (conditional) ratio of the thermal effect to the weight increment. These parameters for estimating the activity of aluminum powders were chosen from the results of nonisothermal oxidation of powders of various particle sizes under conditions of programmed heating (oxidizer–air). In accordance with the testing method proposed, the most reactive powder studied was STPA‐4 ultrafine aluminum powder produced by electrical explosion of conductors.
