The alumina tube in the tube furnace is also called 99 ceramic corundum tube. Its characteristics are as follows.

Alumina industrial ceramic tube is a type of ceramic material with alumina (Al₂O₃) as its main component. Next, we will introduce the corrosion resistance and installation precautions of alumina industrial ceramic tubes.

As a high-performance ceramic material primarily composed of alumina(＞99.3%), corundum tubes have witnessed a surge in demand across advanced industries such as semiconductors, aerospace, and new energy, owing to their exceptional properties including high-temperature resistance, corrosion resistance, and superior hardness.
