Product Description

Zirconia ceramic tubes are tubular components made from zirconium oxide (ZrO₂). They are not ordinary ceramics, but rather represent high-performance technical ceramics or advanced ceramics. Their exceptional properties make them an ideal alternative to metal and other ceramic materials in a variety of harsh environments.

Zirconia ceramic tubes are premium tubular components for high-end industrial applications requiring extreme performance (strength, wear resistance, and high temperature resistance). In demanding environments requiring extreme mechanical stress, abrasion, or impact, zirconia is a more reliable choice than alumina, albeit at a higher cost.


When selecting zirconia ceramic tubes, the following parameters should be considered:

  • Material type: Options include Y-TZP (yttrium-stabilized) and Mg-PSZ (magnesium-stabilized), with Y-TZP being the most commonly used.
  • Dimensional accuracy: Tolerance requirements for inner diameter, outer diameter, length, straightness, and roundness.
  • Surface finish: Typically expressed as Ra.
  • Operating environment: Temperature, media, stress conditions, etc.


Advantages and Applications

The performance of zirconia ceramic tubes stems from the unique properties of zirconia. These tubes offer exceptional mechanical strength and toughness (its flexural strength and fracture toughness are far superior to those of traditional ceramics such as alumina (Al₂O₃), making them less susceptible to brittle fracture and more reliable). They also possess excellent wear resistance, high-temperature resistance, low thermal conductivity, superior corrosion resistance, biocompatibility, electrical insulation, and a low coefficient of thermal expansion.


Due to the aforementioned properties, zirconia ceramic tubes play an irreplaceable role in high-end industrial and technological fields.
