A horizontal stirred ball mill was used. The material of the milling ball was 304 stainless steel. ... The nascent aluminum particles are pyrophoric and will react spontaneously in any oxidizing environment. This leads to the passivation of the particles and the formation of an amorphous oxide (Al 2 O 3) layer on the particle surface [36].
