Since there is very little chance of contamination with ceramics due to erosion, there is no risk of adverse effects on the human body even when used in food-related applications, and there is no metallic odor transferred to the dispersion medium. Further, since there is no risk of dissolution or corrosion even when immersed in an acidic solvent, a wide range of solvents can be selected. Furthermore, when used for dispersing hard materials such as calcium carbonate, the durability of ceramic chips is only about twice that of stainless steel, but when used for dispersing organic pigments and emulsifying water and oil, Approximately 10 times more durable.
