A. Alumina tube is non-flammable, stainless, strong and not easily damaged, and has excellent performance that other organic materials and metal materials cannot match.
B. The abrasion resistance of the alumina ceramic tube is the same as that of corundum, reaching Mohs hardness level 9, and the abrasion resistance is equivalent to that of super hard alloy.

Instructions for use


When using alumina furnace tubes, it is best to control the heating and cooling rate to 5 degrees / minute, the slower the better.
Rapid cooling and rapid heating are one of the main reasons for the rupture of the alumina furnace tube. Our products have good resistance to quenching and heating.

Please keep the alumina furnace tube clean at all times, do not leave some samples in the alumina furnace tube, one side chemical reaction and cracking of the alumina furnace tube. It is recommended to   put the test sample into the crucible and alumina furnace tube.
During lofting and sampling, it is best to be within 200 degrees and slowly push from the edge to the middle. High temperature sample delivery and sampling is also the main reason for corundum tube  rupture.
Make sure to place mullite plugs on both sides of the alumina furnace tube to prevent heat radiation from damaging the silicone ring in the flange. The crucible should be placed in the middle of the alumina furnace tube.
