The Making process of zirconia needle / small ceramic rods : 

1. zirconia powder --- forming--- sintering---machining Outer diameter --- Chamfer ends ---- inspection 

---packing---ship out 

Zirconia ceramic Rods  is the most widely applied and cost effective technical ceramic material. It offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance. The maximum working temperature is up to 1700 °C with relatively high thermal conductivity. It is also an electrically insulating material with a high electrical resistivity. The good corrosion resistance makes it insoluble in water and slightly soluble in strong acid and alkaline solution.

We have both PSZ (partially stabilized zirocnia) and FSZ (fully stabilized zirconia)with high density and good surface roughness.

We can provide Y2O3-ZrO2,CaO-ZrO2,MgO-ZrO2 and also ZTA ceramics.
