Overview of Corundum Crucible

Corundum crucibles, made from alumina (Al₂O₃), are highly valued for their exceptional thermal resistance and chemical stability. These crucibles are ideal for high-temperature applications, such as melting and annealing processes in laboratories and industrial settings. Corundum crucibles can withstand temperatures up to 1800°C and are resistant to most chemical reagents, making them indispensable in various scientific and manufacturing operations.

Features of Corundum Crucible

High Thermal Resistance: Can withstand temperatures up to 1800°C without degrading.

Chemical Stability: Resistant to most acids and alkalis, ensuring minimal contamination during experiments or production.

Durability: Extremely durable and long-lasting, even under harsh conditions.

Non-Reactive: Does not react with the materials being processed, preserving sample purity.

Versatility: Suitable for a wide range of applications including melting metals, glass, and ceramics.

Precision Engineering: Manufactured to tight tolerances for consistent performance and reliability.

Specification of Corundum Mullite Ceramic Sagger Tray Crucible for Refractory Kiln

This Corundum Mullite Ceramic Sagger Tray Crucible is built for tough jobs inside refractory kilns. It holds ceramic pieces during high-temperature firing. The material is key. It uses a mix of corundum and mullite. Corundum gives high hardness and strength. Mullite adds excellent thermal shock resistance. This combination works well under extreme heat.

These crucibles handle very high temperatures easily. They resist temperatures over 1600°C (2912°F). Sudden temperature changes are common in kilns. The crucible withstands these thermal shocks without cracking. This means longer service life and less breakage.

Chemical resistance is another strong point. The crucible fights off attack from many furnace atmospheres and fluxes. This protects the quality of the fired products inside. It keeps contamination low. The dense structure helps here. It minimizes reactions with the materials being fired.

Physical strength is important. These trays support heavy loads during firing. They resist wear and tear from repeated use. Expect good mechanical strength and abrasion resistance. This translates to fewer replacements needed.

Sizes vary to fit different kilns and products. Common shapes are rectangular or circular trays. Dimensions are made to suit specific kiln furniture setups. Standard sizes are available. Custom sizes are often possible too.

Its main use is firing technical ceramics, electronics components, and special refractories. It works in tunnel kilns, shuttle kilns, and roller hearth kilns. The crucible protects delicate items. It ensures consistent, high-quality firing results batch after batch. Performance is reliable under demanding industrial conditions.

Applications of Corundum Mullite Ceramic Sagger Tray Crucible for Refractory Kiln

Corundum mullite ceramic sagger tray crucibles are essential for tough kiln jobs. These containers hold valuable items during high-temperature firing. They are made from a special mix of corundum and mullite. This makes them incredibly strong and heat resistant.

These crucibles handle extreme temperatures easily. Refractory kilns get very hot. These trays stay stable and strong even above 1600°C. They resist melting or warping. This keeps your valuable kiln loads safe inside.

Chemical attack is a big problem in kilns. Glazes, metals, and salts can damage containers. These corundum mullite trays fight chemical erosion well. They protect against aggressive materials. This means the trays last longer. You save money on replacements.

Thermal shock breaks many materials. Sudden temperature changes cause cracks. These sagger trays are different. They handle rapid heating and cooling cycles well. Their structure resists thermal stress. This toughness is crucial for efficient kiln operation.

These trays are perfect for firing technical ceramics. Items like electronics parts need pure conditions. The trays release very little dust. They prevent contamination. Your high-value ceramics stay clean and pure.

Heat treating metal parts is another key use. Metals need precise high-temperature processing. These crucibles withstand the harsh environment. They ensure consistent results batch after batch.

Laboratory testing demands reliability. Researchers need accurate data. These trays provide stable, inert containers for experiments. They offer dependable performance under test conditions.

5 FAQs of Corundum Mullite Ceramic Sagger Tray Crucible for Refractory Kiln

Here are 5 common questions about Corundum Mullite Ceramic Sagger Trays for kilns:

What are these trays made from? They are made from corundum and mullite ceramics. These materials are very hard. They handle extreme heat well. This mix gives excellent strength and chemical stability in kilns.

What temperatures can they handle? These trays can withstand very high temperatures. They typically work well between 1500°C and 1700°C. The exact maximum depends on the specific grade. Always check the manufacturer’s rating for your kiln.

Are they resistant to sudden temperature changes? Yes, they resist thermal shock effectively. The mix of corundum and mullite helps with this. This resistance is vital. Kiln loading and unloading involve rapid temperature shifts. Good thermal shock resistance prevents cracking.

How long do they typically last? Lifespan varies a lot. It depends on the firing temperature, the materials being fired, and how often the trays are cycled. Higher temperatures and corrosive materials shorten tray life. Proper handling and avoiding overloads help them last longer. Expect months to years with careful use.

How should I clean and maintain them? Keep them free of glaze drips and debris after firing. Use gentle mechanical methods for cleaning, like light sandblasting or careful scraping. Avoid harsh impacts. Inspect trays regularly for cracks or significant wear. Replace damaged trays promptly. Good care extends their useful life.
