Reactive alumina powder

Product introduction:
  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 partide size distribution can be designed as unimodal, bimodal or multimodal in favor of improving rtieological 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.
