Introduction Ball milling is generally known as a method to mix, blend, shape and reduce particle sizes. It can also be used as a mechanical synthesis method to produce materials that are milled to extremely fine powders. Several factors, like milling temperature, type of mill, milling speed etc. need to be considered when using ball milling as a synthesis method.

Ball Mills. In ceramics, ball mills are used to grind down materials into very fine particles. Materials such as clay and glaze components can be broken down in a ball mill by getting placed into rotating or rolling jars with porcelain balls inside them. During milling, the porcelain balls pulverized the materials into an incredibly fine powder.
