Corundum Mullite Saggers for Calcination Of 5n Alumina, Indium Oxide Ceramic Powder
Product Features
Our Corundum Mullite Saggers are expertly crafted for the precise calcination of high-purity alumina powder. Fired at an intense 1800℃, these saggers are constructed from 99.9% high-purity alumina (Al2O3) and premium low-sodium white corundum.
With a binder boasting an exceptionally low ash content (≤ 0.01%), we prioritize meticulous control over raw materials. This ensures minimal impurities and optimal high-temperature firing, stabilizing the Al2O3 activity. The result? A saggar with a minimal thermal expansion coefficient and unparalleled chemical purity, perfect for calcining top-grade ceramic powders. Moreover, the sagger’s efficient pore structure facilitates the siphoning effect during low-temperature calcination, ensuring comprehensive and effective organic matter removal.
