Activated Calcined Aluminium Oxide , Metallurgical Grade Alumina Pellets
Calcined Alumina
Raw material and process of production:
AW series α-AL2O3 powder, on the basis of establishing the control model of fine particle size, effectively controls and optimizes the particle size distribution. Meanwhile it makes phase change and surface modification to own small crystal grain size and crystal-like, spherical-like properties.
α-AL2O3 powder has the unique high sintering activity, small grain size, high phase rate, the controllable crystal form and other basic characteristics to make it suitable for castable applications: excellent strength, adequate dense packing, very low water consumption, excellent bulk stability, excellent castable flowability and pumpability. In ceramic industry, it can be easy to sintering, sintered dense, good volume stability and other characteristics.
