Specification of Mullite Sagger Refractory Brick Ceramic Plate Tray High Temperature Refractory Alumina Ceramic Sagger

Mullite sagger refractory bricks are essential kiln furniture. They are ceramic plates or trays. They hold ceramic pieces during high temperature firing. These saggers protect delicate items inside kilns. They face extreme heat directly.

The bricks are made mainly from mullite and alumina. Mullite offers excellent thermal shock resistance. Alumina provides high strength and hardness. This combination is crucial. It ensures the saggers survive repeated heating and cooling cycles without cracking. They withstand temperatures exceeding 1700°C (3092°F). This makes them perfect for firing porcelain, technical ceramics, and advanced materials.

High purity raw materials are used. This minimizes contamination. Your fired products stay clean. The saggers resist chemical attack from glazes and kiln atmospheres. They show low creep rates under heavy loads at peak temperatures. This dimensional stability is vital. It prevents warping or sagging during long firings. Your products remain correctly positioned.

These bricks have a dense structure. It gives them good load-bearing capacity. They stack securely in the kiln. Their low thermal expansion coefficient reduces stress buildup. This directly extends the sagger’s service life. You get more firing cycles before replacement. This saves money over time.

Use these saggers in tunnel kilns, roller hearth kilns, and shuttle kilns. They handle demanding conditions reliably. They offer consistent performance batch after batch. Their durability lowers operational costs. They are a practical choice for industrial ceramic production requiring dependable, long-lasting kiln furniture.

Applications of Mullite Sagger Refractory Brick Ceramic Plate Tray High Temperature Refractory Alumina Ceramic Sagger

Mullite sagger refractory bricks, plates, and trays are essential tools for high-temperature industrial processes. These containers hold materials during intense firing or heat treatment. They are made primarily from mullite and alumina ceramics. This combination gives them exceptional strength and resistance to extreme heat. They withstand temperatures well above 1000°C reliably.

These properties make mullite saggers perfect for firing ceramics. Kilns use them to hold pottery, tiles, and technical ceramics. The saggers protect the items inside. They also prevent contamination from kiln gases or other materials. This ensures product purity. The electronics industry relies on them too. They are vital for sintering electronic components like capacitors and substrates. Precise firing conditions are critical here. Mullite saggers provide the needed stability.

The chemical industry uses these saggers for catalyst processing. They hold catalysts during calcination or regeneration. High purity is essential to avoid poisoning the catalysts. Powder metallurgy benefits greatly. Saggers contain metal powders during sintering. They prevent oxidation and maintain shape. Their thermal shock resistance is a major advantage. They handle rapid heating and cooling cycles without cracking. This durability means they last longer. It reduces downtime and replacement costs.

Their chemical inertness is another key benefit. Mullite saggers resist attack from many fluxes, slags, and molten materials. This protects both the sagger and its contents. They maintain their structural integrity over countless cycles. This reliability translates into lower operating costs. Factories need robust, long-lasting solutions. Mullite alumina ceramic saggers deliver that performance consistently. Industries demanding high-temperature processing trust them daily.
