Высокочистый кальцинированный порошок алюминия огнеупорного класса Al203

Our company's AW series of α-AL2O3 powder is the national project achievement and has passed the national technical appraisal. It uses a unique process and possesses the characteristics of high activity, small grains and high conversion rate. It is the main raw material for the high quality refractory products, as well as fine ceramics and polishing products.

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.

Our 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.
