Zirconia thermocouple protection pipe (ZrO2)

Material: 14.5 wt% Y2O3 + 85.5 wt% Zro2.
Melting point: 2715C.
Temperature range: 0 ~ 2300 ℃.

  • ZrO2
  • MICC


  1, monocrystalline silicon, polycrystalline silicon ingot furnace,  

    semiconductor diffusion furnace, incinerator with a thermocouple protection tube. 

  2, a variety of chemical analysis combustion tube. 

  3, special gas blowing and inhalation tube. 

  4, high temperature handling and so on.

Crystal structure: high temperature for the hexagonal, low temperature for the Quartet.


high temperature, thermal shock performance. High temperature creep resistance performance, shape changes small. Chemical temperature is strong, high temperature has a superior corrosion resistance. Thermocouple protection tube supporting the use of traditional ceramic tube. Because ordinary ceramic tube at high temperature and inert gas is easy to soften and chemical reaction, and zirconia tube and inert gas will not react, thus avoiding the ceramic tube and gas contact, effectively improve the thermocouple life
