Specifications of Corundum Mullite ceramic sagger tray crucible for refractory Kiln battery cathode material

The Diamond Mullite ceramic sagger tray crucible is crafted for high-temperature applications in refractory kilns, especially created for processing battery cathode products such as lithium cobalt oxide (LCO), lithium iron phosphate (LFP), and nickel manganese cobalt (NMC). The product make-up makes up 70– 85% alumina (Al ₂ O ₃) and 15– 25% silica (SiO ₂), developing a corundum-mullite matrix (3Al ₂ O ₃ · 2SiO ₂) with trace additives to enhance thermal and mechanical stability. This high-purity ceramic guarantees minimal contamination, important for cathode material integrity. Physical homes include a density of 3.0– 3.2 g/cm ³, reduced apparent porosity (15%), and great grain structure to resist product seepage. Thermally, it operates continuously at 1600– 1700 ° C, with extraordinary thermal shock resistance, withstanding rapid temperature level changes up to 300 ° C/min without cracking. The thermal expansion coefficient is 5.0– 6.0 × 10 ⁻⁶/ ° C (20– 1000 ° C), ensuring dimensional security, while thermal conductivity ranges in between 5– 6 W/m · K for effective warm circulation. Mechanical toughness consists of a compressive toughness of 200– 300 MPa and flexural stamina of 30– 50 MPa, supporting hefty lots and kiln stacking. Chemically, it stands up to corrosion from liquified salts, alkalis, and acidic settings, preserving inertness versus lithium compounds and transition metal oxides. Criterion measurements are adjustable, with typical trays determining 200– 500 mm in size, 150– 300 mm in width, and 20– 50 mm in density, tailored to kiln setups. The crucible’s reduced porosity and high-density framework stop reactant absorption, guaranteeing consistent sintering problems. Applications focus on calcination and sintering of cathode forerunners, providing longevity under cyclic heating, minimized thermal tension cracking, and extended service life. Compliance with industrial refractory requirements guarantees integrity in high-temperature atmospheres, making it ideal for innovative battery manufacturing calling for precision and contamination-free handling.

Applications of Corundum Mullite ceramic sagger tray crucible for refractory Kiln battery cathode material

Corundum Mullite ceramic sagger tray crucibles are sophisticated refractory services developed for high-temperature applications in kilns, particularly in the manufacturing of battery cathode materials. These crucibles are crafted utilizing a mix of corundum (light weight aluminum oxide) and mullite (light weight aluminum silicate), providing outstanding thermal stability, mechanical strength, and chemical inertness. Their distinct structure makes them perfect for handling the extensive demands of sintering, calcination, and warmth treatment procedures associated with manufacturing lithium-ion battery cathode products such as lithium cobalt oxide (LCO), lithium iron phosphate (LFP), and nickel-manganese-cobalt (NMC) substances.

Trick buildings include a high melting factor (over 1800 ° C), excellent resistance to thermal shock, and reduced thermal growth, making certain structural honesty throughout fast temperature changes. The product’s chemical inertness prevents contamination of delicate cathode forerunners, preserving purity during high-temperature handling. This is critical for attaining regular electrochemical performance in end-use batteries. In Addition, Diamond Mullite’s premium wear resistance expands service life, lowering downtime and substitute expenses in commercial kilns.

These crucibles are widely used in passage kilns, shuttle bus kilns, and rotary heating systems for cathode product production. Their style makes certain uniform heat circulation, lessening hot spots that can deteriorate material high quality. They additionally withstand destructive environments, such as those involving lithium salts or oxygen-rich settings, without cracking or contorting. This dependability supports large-scale, continuous production processes required for electrical vehicle (EV) batteries and power storage space systems.

Compared to typical alumina or silicon carbide crucibles, Corundum Mullite trays supply a balanced mix of sturdiness and cost performance. Their extended lifespan and decreased maintenance requirements make them a lasting choice for suppliers aiming to optimize manufacturing efficiency. Adjustable shapes and sizes even more improve their versatility to details kiln setups and cathode product geometries.

In summary, Diamond Mullite ceramic sagger trays are vital in refractory kiln operations for battery cathode synthesis, delivering unmatched thermal performance, chemical security, and operational longevity to fulfill the expanding demands of the tidy power market.
