5 FAQs of 99% Al2O3 Aluminum Ceramic Alumina Tube with One End Closed

What temperature can this alumina tube handle?
This tube withstands continuous use up to 1600°C. It handles brief spikes slightly higher. Avoid exceeding 1600°C long-term. The material weakens near its limit.

Can it survive rapid temperature changes?
Yes, it resists thermal shock well. It handles sudden temperature differences around 200°C. Avoid very extreme quenches. Gradual heating and cooling are safer for longest life.

What chemicals won’t damage it?
It resists most acids and alkalis. Strong acids like sulfuric and nitric cause little harm. Strong alkalis like sodium hydroxide have minimal effect. Avoid hydrofluoric acid. It attacks alumina aggressively.

How smooth is the tube surface?
The surface finish is very fine. Typical roughness is about Ra 0.4 micrometers. This smoothness reduces contamination. It prevents material sticking during processes.

Where is this tube commonly used?
It’s ideal for high-temperature furnace tubes. It works well for thermocouple protection sheaths. It serves as a crucible for melting small samples. It’s used in semiconductor processing environments. Its closed end contains materials or gases.
