Black zirconia is a material with special properties and great applications. It is made of zirconium oxide (ZrO2), which is given a black appearance by the addition of specific additives and a special process.

Black zirconia ceramic nozzle, along with white aluminum oxide ceramic nozzle, is widely used in automation equipment as a common industrial nozzle. It is manufactured using zirconium oxide as the primary raw material, undergoing a complex process to enhance its wear resistance compared to plastic nozzles. As a result, the service life of black zirconia ceramic nozzles is significantly extended.


Black zirconia nozzles find wide applications across various industries, such as electronics, machinery, and textiles. They are particularly well-suited for use in pick-and-place machines, dispensers, and other automated equipment.


Compared to other types of nozzles, black zirconia nozzles offer several advantages, such as high hardness, wear resistance, corrosion resistance, and non-magnetic properties. They are also lightweight and have a long service life.
