The High Strength Corundum Mullite Kiln Sagger Crucible is a high-performance refractory product engineered to withstand extreme temperatures and harsh firing conditions in industrial kilns and furnaces. Manufactured using a composite material of corundum (α-AlO) and mullite (3AlO·2SiO), this crucible offers a superior balance of thermal stability, mechanical strength, and resistance to chemical erosion and thermal shock.
With a maximum working temperature of up to 1700°C (3092°F), the crucible performs reliably under repeated heating and cooling cycles. It maintains structural integrity and dimensional stability, making it ideal for long-term use in high-temperature sintering environments. The dense microstructure and optimized particle grading reduce porosity and minimize contamination risk, ensuring cleaner processing for sensitive materials.
This sagger crucible is commonly used in the sintering of advanced ceramics, electronic components, magnetic materials, powder metallurgy, and lithium battery cathode/anode materials (such as LFP, NCM, and LCO). It helps protect materials during firing by preventing direct contact with flame or kiln atmosphere, improving product yield and uniformity. The product is available in various sizes, shapes (rectangular, round, custom), and wall thicknesses to meet specific process demands.
Key Features:
High mechanical strength and fracture resistance
Excellent thermal shock resistance
Superior chemical corrosion resistance
Low porosity and long service life
Customizable size and shape for different kiln designs
The High Strength Corundum Mullite Sagger Crucible is an ideal choice for manufacturers seeking durability, precision, and efficiency in high-temperature thermal processing.
