Sintered alumina ultrafine powders

Short Description:

Jingxin can supply series of crystal well developed sintered alumina with different sizes. Ultrafine powders by specially processing them are featured by stable particle size distribution and good  high temperature volumetric stability. Adding them in related refractories imparts them with improved resistances to chemical attack, thermal shock and abrasion. Using surface modified sintered alumina fines or ultra-fines in castables leads to improved rheological behavior and reduced water demand, beneficial to overall properties improvement.
