what is mullite sagger use for?

Our mullite cordierite sagger is a high-performance refractory kiln furniture produced from high-grade mullite and cordierite raw materials through advanced forming and sintering processes. It features outstanding thermal shock resistance, high load-bearing strength at elevated temperatures, excellent corrosion resistance against active cathode materials, and ultra-long service life under cyclic heating conditions.

This sagger is widely applied in the high-temperature sintering process of lithium battery cathode materials, electronic ceramics, magnetic materials, powder metallurgy and rare earth materials. We support full customization of size, shape and material formula to match different kiln types and production processes. As a professional refractory manufacturer with large-scale production capacity, we deliver stable quality, factory-direct pricing and reliable bulk supply for global industrial clients.
