In the process of powder storage, transportation and use, it is often hoped that the nano-aluminum powder exhibits low activity and is less affected by external environmental factors (temperature, humidity, etc.), so that the product has stable performance for a long time. On the other hand, it is desirable to exhibit high activity in solid rocket propellants to obtain high energy release rate and...
