Ball milling synthesis is a combination of physics and chemistry. Through the high-speed vibration and rotation of the ball mill, the hard grinding balls have a strong impact on the raw materials, and a large amount of energy is transferred. During ball milling reaction, grains are refined, powders are activated, and ions are moved.
