Zirconia Ceramic Rods

Zirconia ceramic rods have the advantages of super hardness, high wear-resisting, good corrosion resistance, high temperature tolerance, high strength, high mechanical strength, good chemical stability, polishing surface and so on. Zirconia ceramic rods are stabilized in the cubic crystal structure to avoid cracking and mechanical weakening during heating and cooling.

Product Features:

1) Use temperatures up to 2400 ℃
2) High density
3) High hardness
4) Low thermal conductivity
5) Chemical inertness
6) Resistance to molten metals
7) Good wear resistance
8) High fracture toughness
