Zirconium oxide ceramic rods have excellent performance in hardness, fracture toughness, and corrosion resistance. Our zirconia ceramic rods are precision machined, and the outer diameter accuracy can reach ±0.002mm, and the surface roughness can reach Ra0.025.
Basic properties of zirconia ceramics
Zirconium oxide generally refers to zirconium dioxide, with the chemical formula ZrO2, which is the main oxide of zirconium. It is usually white, odorless, and tasteless crystals, and is difficult to dissolve in water, hydrochloric acid, and dilute sulfuric acid.
-High density – up to 6.05g/cm³
-High bending strength and hardness
-Excellent fracture toughness – impact resistance
-Good friction performance
-Low thermal conductivity – close to 10% of alumina
-Acid and alkali corrosion resistance
-Elastic modulus similar to steel
-Thermal expansion coefficient is similar to iron
Advantages of zirconia ceramic rods
Zirconium oxide ceramic rods have high strength, wear resistance, and flexibility, far exceeding most advanced ceramics. Zirconia ceramics are very strong industrial ceramics with excellent performance in hardness, fracture toughness, and corrosion resistance.
Applications of Zirconia Ceramics
There are several types of zirconia ceramics, the most common being yttria partially stabilized zirconia (Y-PSZ) and magnesium oxide partially stabilized zirconia (Mg-PSZ). Its unique resistance to crack growth and high thermal expansion make it an excellent material for joining ceramics with metals such as steel. Due to the unique properties of zirconia, it is sometimes referred to as “ceramic steel”.
