Specifications of High Al203 corundum mullite saggar crucible kiln shelves refractory alumina ceramic sagger tray for furnace

High Al2O3 diamond mullite saggar crucible kiln shelves are refractory alumina ceramic trays made for high-temperature commercial furnace applications. These parts deal with severe warm and extreme conditions reliably. The primary material is high-purity light weight aluminum oxide (Al2O3), integrated with mullite and diamond. This mix makes sure strong thermal stability and resistance to chemical rust. The alumina material usually goes beyond 85%, enhancing toughness under duplicated home heating cycles.

These sagger trays run in temperature levels approximately 1750 ° C. They stand up to thermal shock properly, stopping splits throughout rapid temperature changes. Their thick framework minimizes porosity, decreasing slag infiltration and expanding life span. The trays can be found in basic sizes like 300x300mm or 400x400mm, with densities varying from 25mm to 50mm. Custom measurements are available for specific furnace arrangements.

The high mechanical toughness supports hefty lots without deformation. This is essential for holding porcelains, metals, or digital elements throughout shooting. The product’s reduced thermal conductivity boosts energy performance by preserving heat within the heater. Chemical resistance to acids, antacid, and molten steels makes certain minimal destruction in time.

Manufacturing involves advanced sintering techniques to achieve consistent thickness and marginal problems. Precision shaping guarantees flat surface areas, important for secure piling in kilns. These trays fit industries like porcelains, metallurgy, and battery material manufacturing. They change conventional silica or cordierite racks, supplying longer life expectancy and reduced downtime.

Upkeep is uncomplicated due to the non-reactive surface area. Particles or polish spills tidy conveniently without harming the tray. The lack of binders or ingredients protects against contamination of terminated items. Compatibility with oxidizing and lowering environments makes them functional for diverse processes.

Personalized styles accommodate unique heating system formats or specialized thermal profiles. Options include added reinforcement ribs or customized side configurations. These trays are affordable long-term services, reducing substitute regularity. Performance consistency makes sure stable production high quality across batches.
