Item Number: TA60D800

2 3/8" OD larger diameter Alumina tube with high purity 99.5% Al2O3 material. Such an alumina tube can be used at operating temperatures to 1700 oC in both oxidizing and reducing atmospheres. Tubes have been evacuated to 10-7 Torr at room temperature. It proves inert to carbon and refractory metals in many severe situations:


Purity Al2O3 > 99%, SiO2 < 0.25%, CaO+MgO < 0.3%
Density > 3.91 g /cm3
I.D 2"+/- 0.08'' (51 +/- 2 mm)
O.D 2-3/8"+/- 0.04'' (60.6 +/- 1 mm)
Length 800 mm (31.5")
Detailed dimension drawing
Max. working temperature 1700 oC
  • Please don't use alumina tube under vacuum at temperature > 1500 oC
  • McDanel strongly recommends ramp rate less than 100oC/ hour in case of large diameter or thick wall tube
  • Please keep thermal gradient less than 100oC/ inch to avoids cracking
  • Please handle the tube carefully. Warranty does not include the tube (only for the machine itself)
  • Please separate parts from the inside surface of the tube to avoid thermal shock
