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

This porous alumina ceramic tube and rod handles extreme heat reliably. Its main material is pure aluminum oxide. This ensures top performance in high temperature settings. The composition gives outstanding heat resistance. It withstands temperatures reaching 1800°C. This makes it perfect for intense industrial processes. Furnace linings and kiln furniture benefit greatly. Thermal processing equipment needs such durable parts. The material maintains strength under constant heat stress. It does not soften or deform easily.

A key feature is its high porosity level. The structure contains many tiny air pockets. Porosity typically ranges between 95% and 99%. This high porosity provides excellent thermal insulation. Heat transfer slows down significantly. Energy efficiency improves for high-heat applications. The air pockets also make the product very lightweight. Handling and installation become simpler. Reducing structural load is possible. Despite being porous, the ceramic retains good mechanical strength. It handles physical stress adequately.

The product form is either a hollow tube or a solid rod. Both shapes serve various industrial needs. The hollow tube design is common. It allows gases or fluids to pass through safely. Sensors or heating elements often fit inside. The solid rod provides robust support structures. Mounting thermocouples is one typical use. Custom sizes and dimensions are usually available. Length, diameter, and wall thickness can vary. Specific project requirements guide the choice.

Its primary use is anywhere demanding extreme heat resistance plus insulation. Metal heat treatment furnaces rely on it. Semiconductor manufacturing equipment incorporates these ceramics. Laboratory test rigs exposed to high temperatures need it. Aerospace components sometimes use this material. Chemical processing plants value its inertness. The ceramic resists attack from many corrosive substances. Long service life under harsh conditions is expected. Minimal maintenance is another advantage. It offers a practical solution for severe thermal environments.

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

Porous alumina ceramic tubes and rods deliver serious heat resistance. They handle extreme temperatures easily. Their composition is mostly aluminum oxide. Common purity levels are 95% and 99%. This high alumina content gives them strong refractory properties. They stand up to very hot environments without breaking down.

The unique porous structure is key. Air fills the many tiny holes inside the material. This trapped air makes excellent insulation. Heat struggles to pass through. These tubes shield sensitive parts from intense heat. They work well in furnaces, kilns, and high-temperature sensors. Thermal insulation is a major job for them.

Their hollow shape matters too. It makes them lighter than solid pieces. This saves weight in big systems. The hollow center also creates a path. Gases or liquids can flow straight through. This is useful for directing hot air or exhaust.

The pores do more than insulate. They allow gases to pass through the tube walls. This makes them good filters. They trap particles from hot gases. You see this in filtration systems for dirty exhaust streams. The large surface area from the pores is also helpful. It provides space to hold coatings. Catalysts often coat these tubes. The coated tubes then drive chemical reactions in hot conditions.

These alumina parts are tough. They resist chemical attack from many substances. They survive rapid heating and cooling cycles well. This thermal shock resistance is vital. Industrial processes often have big temperature swings. The tubes don’t crack easily. They last for years in harsh settings.

Their strength holds up at high heat. They won’t bend or deform under typical loads. You find them supporting other furnace parts. They hold heating elements or thermocouples securely. The 99% pure tubes handle the most extreme heat. The 95% tubes offer a cost-effective choice for slightly lower temperatures. Both types work reliably in demanding industrial applications. They solve heat problems in many settings.

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

What are these alumina ceramic tubes?
These are tubes made from aluminum oxide. They are hollow inside. They have many tiny holes through the material. This makes them porous. The porosity level is very high, either 95% or 99%. This means most of the tube is empty space.

Why is high porosity important?
High porosity makes these tubes very light. It also gives them a large surface area inside the tiny holes. This large surface area is useful. It helps in filtering hot gases or liquids. It aids in catalyst support applications. The holes let fluids pass through while the ceramic structure stays strong.

How heat resistant are they?
They are extremely heat resistant. This is a key feature. They handle very high temperatures well. They are made for demanding thermal environments. They resist thermal shock. This means they won’t crack easily when heated or cooled fast. They maintain their shape and structure under intense heat.

Where are they typically used?
These tubes are used in high-temperature settings. Common uses include industrial furnaces. They work in kilns and reactors. They serve as thermocouple protection sheaths. They act as radiant burner tubes. They are used for gas filtration at high heat. They are found in labs and research equipment needing heat resistance.

What sizes and shapes are available?
They come as tubes or solid rods. Tube diameters vary. Wall thicknesses differ. Lengths can be customized. Standard sizes exist. Specific dimensions depend on the porosity level and the intended application. Both 95% and 99% porous versions are offered.
