2 3/8" x 31 1/2" (60 OD x 51 ID x 800mm L) Alumina Ceramic Tube - EQ-TA-60D-M800

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: SPECIFICATIONS

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
Warning	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
