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.
