Saggers play an important role in the calcination of lithium battery cathode materials. During repeated firing cycles, the sagger must withstand rapid temperature changes, chemical erosion, powder loading and long-term high-temperature operation.
GUOLIANG Mullite Cordierite Sagger combines mullite's high-temperature strength with cordierite's low thermal expansion and thermal shock stability, making it suitable for demanding battery material sintering processes.
Typical applications include:
Repeated heating and cooling can cause cracking and structural damage in kiln furniture. The low thermal expansion and thermal stability of our mullite cordierite material help the saggar withstand repeated firing cycles.
An ultra-low coefficient of thermal expansion helps minimize dimensional changes during temperature fluctuations and contributes to stable operation during continuous production.
The material provides resistance to chemical attack under demanding firing conditions, helping reduce premature deterioration of the saggar.
Good structural stability at elevated temperatures helps maintain the geometry of the saggar during long firing cycles and repeated kiln loading.
Controlled material composition helps reduce unwanted contamination during battery material calcination, an important consideration in high-purity new energy material production.
Good heat-transfer performance supports more uniform heating of the material inside the saggar and can contribute to efficient kiln operation.
GUOLIANG supplies both mullite cordierite and SiC saggars for new energy material processing.
Mullite Cordierite Saggar is particularly suitable where low thermal expansion, thermal shock stability and stable repeated firing performance are important.
SiC Saggar can be considered for applications requiring higher thermal conductivity and demanding high-temperature mechanical performance.
The appropriate material should be selected according to firing temperature, kiln atmosphere, processed material and expected operating conditions.
Battery material production lines may use different kiln systems, loading methods and sagger dimensions. GUOLIANG provides custom Mullite Cordierite Saggars according to customer production requirements.
Customization can include:
For replacement projects, customers can also provide an existing sagger drawing or sample for technical evaluation.
GUOLIANG specializes in refractory and high-temperature material solutions for industrial applications. Our technical and production teams support customers from material selection and product design through manufacturing and application.
For battery material manufacturers, we focus on matching the Mullite Cordierite Saggar with actual kiln conditions, thermal cycles and material chemistry to achieve stable production performance.
