99% Alumina Mullite Corundum Sagger

Our 99% alumina mullite corundum sagger is a premium-grade refractory kiln furniture manufactured from high-purity alumina (99% Al₂O₃), mullite and corundum raw materials via precision forming and high-temperature sintering processes. It features exceptional high-tem

perature resistance, outstanding thermal shock stability, excellent corrosion resistance against active cathode materials and glass phases, and superior load-bearing strength under continuous high-temperature operating conditions.

This high-purity corundum sagger is ideally suited for demanding sintering processes in lithium battery cathode materials, electronic ceramics, precision structural ceramics, rare earth materials, powder metallurgy and magnetic materials. It maintains stable performance and ultra-long service life even under cyclic high-temperature heating environments. We support full customization of dimensions, shapes and material formulas to match various kiln types and specialized production processes. As a professional refractory manufacturer with advanced production facilities, we deliver consistent premium quality, factory-direct pricing and reliable bulk supply for global high-end industrial clients.
