Specification of High Quality 90% 99% Refractory Alumina Ceramic Ball High Alumina Corundum Balls for Industry Kiln Furnace

These high quality alumina ceramic balls work hard in tough kiln and furnace conditions. They come in two main grades: 90% alumina and 99% alumina. Both types offer excellent heat resistance and strength.

The 90% alumina balls are a reliable, cost-effective choice. They contain at least 90% aluminum oxide (Al2O3). This makes them very dense and hard. They handle temperatures up to 1650°C (3000°F) well. Their high crush strength resists breaking under load inside hot furnaces. These balls provide good chemical stability against many corrosive materials. They are a solid solution for many general high-temperature jobs.

The 99% alumina balls, often called corundum balls, offer top performance. They contain over 99% pure aluminum oxide. This extreme purity gives them superior properties. They withstand even higher temperatures, exceeding 1750°C (3180°F). Their density is greater. Their hardness is exceptional. Their resistance to wear and chemical attack is outstanding. This makes them perfect for the most demanding furnace zones and aggressive chemical environments. They last longer under severe stress.

Both grades are made from fine, pure raw materials. They are formed precisely and fired at ultra-high temperatures. This process creates a stable, crystalline structure. The result is a product with low porosity. Low porosity means less gas absorption. It also means better resistance to thermal shock and corrosion. These balls maintain their shape and size under intense heat. They won’t easily crack or spall. This dimensional stability is crucial for consistent furnace operation.

Industrial kilns and furnaces use these balls extensively. They support catalyst beds effectively. They cover burner nozzles reliably. They act as inert packing media efficiently. You find them in petrochemical plants, refineries, ceramic factories, and steel mills. They are essential wherever high heat and harsh chemicals are present. They keep industrial processes running smoothly and efficiently.

Applications of High Quality 90% 99% Refractory Alumina Ceramic Ball High Alumina Corundum Balls for Industry Kiln Furnace

These high alumina ceramic balls are essential for industrial kilns and furnaces. They are made from pure alumina powder. The alumina content is high, typically 90% or 99%. This makes them incredibly strong and durable. They withstand extreme heat very well. These balls are called refractory because they handle high temperatures without breaking down. They are also known as corundum balls due to their composition.

Their main job is supporting products during firing. They act as kiln furniture. Placing items on these balls allows heat to circulate freely. This prevents uneven firing. It stops warping or cracking in the final products. Factories making ceramics, tiles, and sanitaryware rely on them heavily. These balls are also vital in catalyst support grids within chemical plants. They hold catalyst materials securely. They let gases flow through effectively.

These balls offer significant advantages. Their heat resistance is exceptional. They operate reliably in temperatures over 1600°C. Their wear resistance is also outstanding. They last much longer than cheaper alternatives. This reduces replacement costs and downtime. They resist chemical corrosion too. Harsh furnace atmospheres or chemical processes don’t damage them easily. Their dimensional stability is excellent. They keep their shape and size cycle after cycle. This ensures consistent product spacing and quality.

The high density of these balls is crucial. It provides the necessary mechanical strength. It prevents crushing under heavy kiln loads. Their smooth surface minimizes marking on delicate fired goods. Industries beyond ceramics use them. These include metallurgy for heat treatment, chemical processing for reactors, and environmental technology for air pollution control systems. They are fundamental for efficient, high-temperature industrial operations. They guarantee product quality and process reliability.

5 FAQs of High Quality 90% 99% Refractory Alumina Ceramic Ball High Alumina Corundum Balls for Industry Kiln Furnace

These alumina ceramic balls are tough industrial helpers. They go inside kilns and furnaces. They handle extreme heat and keep things working well. People often ask these questions.

What exactly are these balls? They are round balls made from special alumina powder. The powder gets pressed and fired at very high temperatures. This makes them super hard and heat resistant. They are used as supports or fillers inside hot furnaces.

Why is 90% or 99% alumina important? The number shows how much pure alumina is inside. More alumina means a tougher ball. A 99% ball handles much hotter temperatures than a 90% ball. It resists chemicals better. It lasts longer under heavy use. Choose the percentage based on your furnace needs.

How hot can these balls get? The 90% balls typically work up to about 1650°C. The 99% balls handle even more heat, usually up to 1800°C. They keep their strength at these temperatures. They don’t melt or crack easily.

How are they better than regular ceramic balls? Regular balls might break down faster. They might not handle such high heat. These high alumina balls are much stronger. They resist wear and corrosion far better. They last much longer saving money.

Where are they used most? You find them supporting products in kilns firing ceramics or tiles. They fill towers in chemical plants processing hot gases. They are inside furnaces making steel or glass. They stop tanks from warping. They insulate heat effectively.
