Reactive alumina powder

Short Description:

Reactive alumina is made through specially calcination, then fully fine-grinding and multistage powder size seperation. The particle size can be controlled in the range of microns and submicrons. The particle size distribution can be designed as unimodal, bimodal or multimodal in favor of improving rheological properties and sinterbility of castables, reducing water demand, enhancing mechanical strength, improving abrasion resistance and high temperature performance, which enables the product to be indispensable raw material for high performance refractories and electronic ceramics.

Size availability:

Powders from under 20 to 2μm can be provided.

Product package:

25kg/bag or other packages as per users’ requirements are available.
