High temperature resistance Corundum Mullite Ceramic Sagger for 1650℃ Firing

Our Corundum Mullite Ceramic Sagger is a premium refractory solution meticulously engineered to excel in extreme thermal environments, specifically designed to withstand continuous firing temperatures of up to 1650℃.
Exceptional Performance Characteristics
The superior performance of this sagger stems from its advanced composite structure, combining the high refractoriness of corundum with the thermal shock resistance of mullite.

High-Temperature Stability: With a Refractoriness Under Load (RUL) exceeding 1650℃, it maintains incredible mechanical strength under heavy loads, allowing for efficient, tall stacking without deformation.
Thermal Shock Resistance: The mullite component ensures a low coefficient of thermal expansion, enabling the sagger to endure rapid heating and cooling cycles without cracking, significantly extending its service life.
Chemical Inertness: Highly resistant to corrosion from alkalis and metal oxides, its inert surface prevents reactions with glazes or powders, ensuring a pristine firing environment.

Versatile Industrial Applications
Designed for rigorous kiln operations, our sagger is the ideal choice for the sintering of advanced technical ceramics, lithium battery cathode materials (such as NCM and LFP), electronic ferrites, and high-grade porcelain. It is perfect for any process where dimensional stability and zero contamination are non-negotiable.
