5 FAQs of High Precision Mirror Polished Al2O3 Alumina Ceramic Tube

What exactly is this ceramic tube?
It’s a tube made from pure Al2O3 alumina ceramic. This material is super hard and resists chemicals well. The surface gets a special mirror polish treatment. This makes it incredibly smooth and shiny.

Why is the mirror polish important?
The ultra-smooth finish prevents material sticking to the tube surface. This smoothness stops contamination. It also cuts friction dramatically. Low friction means less wear and better flow inside the tube.

How hot can these tubes get?
These Al2O3 tubes handle very high temperatures easily. They work perfectly fine up to 1600°C (2912°F). Their strength stays high even when hot. This makes them great for furnaces or high-heat processes.

How do I clean a polished tube safely?
Use gentle cleaning methods. Warm soapy water works well most times. Avoid harsh chemicals or abrasive scrubbers. These could scratch the polished surface. Rinse the tube thoroughly with clean water after cleaning.

Can I get tubes in different sizes or shapes?
Yes, custom orders are possible. We make tubes in various diameters, lengths, and wall thicknesses. Special shapes beyond simple tubes might be available too. Ask our team about your specific size or shape needs.
