In order to improve nano-aluminized solid propellant properties and performance, different materials are being investigated for coating nano-aluminum particles. Two of the powders which are considered are V-ALEX, a fluoropolymer (Viton) coated nano-aluminum, and L-ALEX, a stearic acid coated nano-aluminum. It is believed that a thin layer of coating should protect the aluminum core from premature oxidation, as well as provide an exothermic source which may accelerate particle ignition, resulting in reduction of agglomeration.

含有不同纳米铝粉的复合推进剂中的团聚

为了改善纳米镀铝固体推进剂的性能和性能，正在研究用于涂覆纳米铝颗粒的不同材料。考虑的两种粉末是 V-ALEX，一种含氟聚合物 (Viton) 涂层的纳米铝，和 L-ALEX，一种硬脂酸涂层的纳米铝。据信，薄涂层应保护铝芯免于过早氧化，并提供可加速粒子点燃的放热源，从而减少团聚。
