High-Performance Corundum Mullite Saggers For 5N Alumina & Indium Oxide Calcination
Product Highlights
Engineered for the precise calcination of high-purity ceramic powders, including 5N alumina and indium oxide, our Corundum Mullite Saggers excel in both performance and durability. Manufactured at a high firing temperature of 1800℃, they incorporate 99.9% ultra-pure alumina (Al2O3) and top-grade low-sodium white corundum.
Key benefits include:
Exceptional Material Composition: Crafted from 99.9% pure alumina and superior low-sodium white corundum.
Robust High-Temperature Processing: Fired at 1800℃ to ensure enhanced strength and stability.
Low Impurity Binder: Uses binders with minimal ash content (≤ 0.01%) to maintain high chemical purity.
Optimized Al2O3 Activity: Rigorous quality control during material selection and firing guarantees reduced thermal expansion and greater chemical integrity.
Innovative Pore Structure: Promotes a siphoning effect during low-temperature calcination, ensuring comprehensive removal of organic compounds.
These advanced features make our saggers ideal for demanding applications that require both thermal stability and chemical purity.
