Ammonia nitrate, potassium chloride, and aluminum powder.

硝酸氨 氯化钾 还有铝粉。

The nuclear reactions in " Oppenheimer" were also created by producing actual explosions (albeit not nuclear ones), brightened by aluminium and magnesium powder.

《奥本海默》中的反应也真正的()，用了铝粉和镁粉使发光。

For example, aluminum powders are preferred for glass surfaces and brass, whereas granulated jet black powder is used on silvery surfaces to create better contrast.

例如，铝粉玻璃表面和黄铜的首选，而粒状喷射黑粉用于银色表面以产生更好的对比度。
