December 20, 2015. Advantages. Ceramic microstructures enjoy covalent bonding inherent between non-metal elements. This means they share electrons. This atomic co-operation yields a very strong attraction force and because of this, ceramics offer a series of benefits in comparison to metals. They normally have a very high hardness (70-90 HRc ...

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.
