Corundum Mullite Saggers are high-performance refractory products made from a blend of corundum (Al₂O₃) and mullite (3Al₂O₃·2SiO₂). refractory kiln furniture corundum sagger boxes are engineered to deliver excellent high-temperature resistance, superior thermal shock resistance, and outstanding chemical stability, making high thermal shock sagger suitable for long-term use in extreme conditions. With a low thermal expansion coefficient and high compressive strength, alumina mullite composite saggers maintain structural integrity even under intense heat and mechanical stress, ensuring reliable performance in the most demanding environments.
