Specification of Alumina Ceramic Foam Plates

Alumina ceramic foam plates offer unique properties. They are made from aluminum oxide ceramic. This material is very strong. It resists wear well. It handles high temperatures easily. These plates have an open-cell foam structure. This structure contains many interconnected pores. The pores are like tiny tunnels. They run through the whole plate. This open structure is key to how they work.

The porosity is usually high. It often ranges from 80% to 90%. This means most of the plate is empty space. The pore size can be controlled. Manufacturers make different sizes. Common sizes are between 0.5mm and 10mm. You choose the size based on your needs. The surface area inside is very large. This is because of all the tiny pores.

These plates handle extreme heat. They withstand temperatures up to 1700°C. They are very stable under heat. They don’t change shape much. They resist thermal shock well. Thermal shock means sudden temperature changes. This makes them reliable in tough conditions. They are also chemically inert. Most chemicals don’t affect them. Acids and bases don’t damage them easily.

People use them for many jobs. They are excellent filters. They filter hot gases and molten metals. The open pores trap particles. Clean fluid flows through. They work in high-temperature environments. They distribute gas evenly. They act as flame arrestors. They stop flames from spreading. They are good catalyst supports. Catalysts attach to the large surface area. They provide lightweight insulation. They protect equipment from heat. They find use in furnaces, foundries, and chemical plants. They are also used in aerospace and energy sectors.

Applications of Alumina Ceramic Foam Plates

Alumina ceramic foam plates serve many important jobs. They filter dirty molten metal well. Foundries rely on them for cleaner castings. They remove unwanted bits from aluminum and iron. This makes stronger final metal parts. Metal processors use these plates too. They handle hot liquid metal effectively. The plates support metal during heat treatment. They resist extreme furnace temperatures reliably. Chemical plants find them very useful. Alumina foam plates hold catalysts securely. Their open structure lets gases pass freely. This boosts chemical reactions efficiently. Thermal insulation is another key use. These plates block heat transfer effectively. They protect equipment in high heat areas. Furnace linings often include them. Their porous nature traps heat well. Battery and fuel cell makers use them also. They work as porous electrodes or supports. The structure allows good electrical flow. This improves energy device performance. Engineers pick these plates for harsh conditions. They withstand corrosion and wear consistently. Their high temperature stability is proven. Many industries trust alumina ceramic foam.

5 FAQs of Alumina Ceramic Foam Plates

Here are 5 FAQs about Alumina Ceramic Foam Plates:

What are Alumina Ceramic Foam Plates?
These plates are made from aluminum oxide. They have a foam-like structure full of tiny holes. This structure is rigid and highly porous. It’s created by replicating a polymer foam template. The result is a strong ceramic plate with many connected pores.

What are they used for?
People mainly use these plates for filtering molten metals. They remove impurities. They are also used in chemical processing as catalyst supports. Thermal insulation is another common application. Their open pores handle high temperatures and corrosive environments well.

Why choose them over other filters?
They handle extreme heat very well. They resist chemical corrosion effectively. Their structure provides high surface area. They trap particles well. They last longer than many alternatives. Their strength under pressure is good.

How are they different from other ceramics?
The key difference is their unique foam structure. This structure has open, interconnected pores. Regular ceramics are usually dense. These plates let fluids pass through while trapping solids. Their porosity is much higher than solid ceramic tiles.

Are they difficult to handle?
Handle them carefully. They are strong but can be brittle. Avoid impacts or dropping them. Their surface is hard and abrasive. Wear gloves during installation. Cutting or machining requires special tools. Follow the manufacturer’s handling instructions.
