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

People often ask about these porous alumina ceramic tubes and rods. Here are some common questions.

What is special about these tubes? They are mostly air inside. About 95% to 99% of their structure is tiny holes. This makes them very light. It also means they trap heat well. They are good insulators. They are made from alumina powder shaped into tubes or rods. Then they are baked at high temperatures. This creates the strong, porous structure.

Why is high alumina important? Alumina is aluminum oxide. It handles heat well. It stays strong even at high temperatures. It doesn’t react easily with most chemicals. It lasts a long time. Using high-purity alumina (Al2O3) means better performance. It keeps its shape under thermal stress. It resists wear and corrosion.

How hot can they get? These tubes handle very high temperatures. They are designed for intense heat. They work reliably up to about 1700 degrees Celsius. This depends on the exact purity and structure. They resist sudden temperature changes too. They won’t crack easily from thermal shock. They are stable for long periods in hot environments.

Where are they used? People use them where heat is a problem. They are found in furnaces and kilns. They act as insulation liners. They protect thermocouples and sensors. They are supports for heating elements. They are used in lab equipment. They are good for gas filtration in hot gases. They work in metal processing. They are common in aerospace testing. Any place needing lightweight, heat-resistant parts might use them.

How do I handle them? Be careful. They are strong but brittle. Avoid dropping them. Avoid strong impacts. They can break. Protect them from sharp knocks. Store them safely. Handle them gently during installation. They resist chemicals well. But very strong acids or alkalis could damage them over time. Check the specific chemical resistance for your use.
