Performance: Using high quality raw materials, calcined alumina is being produced in the rotary kiln on the reasonable temperature, with the characteristic of high conversion rate, stable crystallization and low impurity content. Its products have excellent performance of high mechanical strength, stable shrinkage rate, good electrical insulation, high wear resistance, and outstanding corrosion resistance. Application 1.Refractories, refractory binder 2.Abrasives and fine polishing 3.High-alumina ceramic, highalumina glaze, glass, cutting tools, ordinary alumina ceramic 4.Insulating firebrick and electronic component 5.Thermal conductivity of plastic, rubber, adhesives and coatings Certificate: Iso9001:2008, iso14001:2004, ohasas18001:2007, sgs.
