5 FAQs of Refractory Heat Resistance High 95% 99% Porous Hollow Al2o3 Alumina Ceramic Tube/rod

What makes these alumina tubes special?
They contain over 95% alumina. Some reach 99%. This high purity gives them extreme heat resistance. They handle very high temperatures well. Their structure is porous. They are also hollow. This design is key for specific uses.

How hot can they get?
These tubes resist intense heat. They work reliably in temperatures exceeding 1500°C. The exact limit depends on the alumina grade. 99% alumina handles higher heat than 95%. They keep their shape and strength even when very hot.

Why the porous structure?
The tiny holes serve a purpose. Porosity allows gases or liquids to pass through the tube wall. Think filtration. Think catalyst supports. The holes are controlled. This ensures consistent flow. The hollow center provides extra space inside.

Where are they typically used?
They suit harsh industrial environments. Common uses include furnace linings. They act as thermocouple protection sheaths. They are used in kiln furniture. They work in molten metal filtration. They support catalysts in chemical reactions. Heat is always a factor.

Are they fragile?
They are ceramic. They can break if hit hard. They resist thermal shock better than many dense ceramics. The porous structure helps. It absorbs some stress from rapid temperature shifts. Handle them carefully. They perform well under steady, high heat.
