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

These porous alumina ceramic tubes and rods provide extraordinary high-temperature performance. They are made from high-purity aluminum oxide (Al2O3). This material gives them exceptional refractory homes. They hold up against extreme warm without degrading. Temperature levels exceeding 1700 ° C (3092 ° F) are no worry. Their crucial feature is managed porosity. The structure contains lots of little, interconnected pores. This develops a large surface area inside the material. Porosity degrees usually reach 95% or perhaps 99%. This high porosity makes them extremely light-weight. It also supplies superb thermal insulation. Warmth transfer slows down considerably. This safeguards surrounding components from extreme warm.

The hollow tube or solid pole shapes are functional. They are generally used as heater liners, thermocouple defense sheaths, and burner elements. Their porous nature allows controlled gas circulation. This is important for processes like gas filtering or aeration. They withstand thermal shock well. Abrupt temperature adjustments trigger much less anxiety. This reduces splitting and failure. Chemical resistance is one more significant advantage. Acids, antacid, and molten steels cause little damages. This makes certain lengthy life span in rough settings. The high alumina web content guarantees stability. It protects against warping or softening under load. Mechanical toughness remains great regardless of the porosity. The material is inert and non-toxic. It is suitable for delicate applications like food handling or pharmaceuticals.

These elements are ideal for requiring industrial settings. Steel handling, chemical plants, and warmth therapy heating systems rely upon them. They do accurately as kiln furniture, stimulant supports, and insulators. Their one-of-a-kind mix of warm resistance, porosity, and chemical inertness is hard to match. They give a sturdy, reliable option for handling extreme warm and harsh conditions. Engineers choose them for critical thermal administration tasks.

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

Refractory Heat Resistance High 95% 99% Porous Hollow Al2o3 Alumina Ceramic Tube/Rod FAQs

What temperature can these tubes handle? These tubes resist very high heat. They work reliably long-term up to 1600°C (2912°F). They handle even higher short-term spikes. This makes them good for demanding furnace jobs.

Why is the tube porous? The holes serve a purpose. The porosity allows gases or liquids to pass through the tube wall. This is essential for jobs like filtering hot liquids, distributing gases evenly inside furnaces, or acting as a diffuser.

Does 95% or 99% purity matter? Yes, it affects performance. The 99% Al2O3 tube offers better heat resistance. It resists chemical attack better too. It handles the highest temperatures best. The 95% tube is still very strong. It costs less. Choose 99% for the most extreme conditions.

Are these tubes fragile? Alumina ceramic is hard but brittle. Handle it carefully. Avoid sharp impacts or drops. Sudden temperature changes can crack it. Heat it up and cool it down slowly. This prevents thermal shock damage.

Can I get custom sizes or shapes? Yes, custom orders are possible. Manufacturers often make tubes to specific lengths, diameters, and wall thicknesses. They can adjust the porosity level. Discuss your exact needs with the supplier. They can advise on feasibility.
