Advantages of Ball Milling Process. Produces uniform particle sizes Ball milling process ensures particles are all the same size, enhancing consistency in the end product. This uniformity in size helps in maintaining quality control. Low operation cost It is also a costeffective operation. The cost of running and maintaining the equipment is low, making it a budgetfriendly choice.

For milling time, the ball milling process was interrupted at a regular interval of 10 h for powder extraction and characterization, up to a total milling time of 60 h. It is worth noting that a small ball (which weighs ~1 g) is removed at every g of powder extraction to maintain the balltopowder ratio.

1. Introduction. High energy ball milling (HEBM) is known as an economic, simple and yet powerful method for the production of nanostructured and amorphous materials [1].The prolonged milling of powder mixtures, results in the formation of supersaturated solid solution, nonequilibrium intermetallic compounds as well as the formation of silicides, nitrides, stable or unstable carbides [2].

The duration of ball milling greatly influences the characteristics of highsiliconaluminum composite during the ball milling process. This study examines how the microstructure, thermal conductivity, and hardness of a highsiliconaluminum composite are affected by different ball milling times. We exposed the powder to various durations of ball milling and employed different pellet ratios.

Ball milling is a mechanical technique that is broadly used to grind powders into fine particles [134141]. The reactants are generally broken apart using solvent molecules in the traditional method; but in ball milling, reactants are broken by using mechanical forces. The term mechanochemistry has been introduced very recently [142].
