KES Series KA Part

KES Series KA Part KES series means ultrafine functional alumina and easy sintered alumina. The raw materials are calcined alumina for sintering and low soda alumina. After milling process, it is classified to three grade as like low soda, medium soda and normal soda by soda content.They are widely used for alumina ceramics in the industry of electro-ceramics by the characteristics of heat-resistance, chemical stability, high strength, abrasion-resistance, electro-insulation and etc. Specifications Product name KAM KES-L1 KES-L2 KES-M1 KES-M1 KES-N1 KES-N2 ChemicalProperties Al2O3(%) MIN 99.6 MIN 99.6 MIN 99.6 MIN 99.7 MIN 99.7 MIN 99.6 MIN 99.6 Na2O(%) Max 0.30 Max 0.10 Max 0.10 Max 0.20 Max 0.20 Max 0.30 Max 0.30 SiO2(%) Max 0.02 Max 0.06 Max 0.06 Max 0.04 Max 0.04 Max 0.02 Max 0.02 Fe2O3(%) Max 0.02 Max 0.02 Max 0.02 Max 0.02 Max 0.02 Max 0.02 Max 0.02 Loss on Ignition(%) Max 0.2 Max 0.2 Max 0.2 Max 0.2 Max 0.2 Max 0.2 Max 0.2 PhysicalProperties Dp50(µm) 3~4 0.6 2.5 0.6 2.3 0.6 2.5 Alpha size(µm) 2~4 0.3~0.4 0.4~0.5 0.4 0.4~5.0 0.3 0.3~4.0 Specific surface area(m2/g) 1.0 6.0 3.0 6.0 3.5 6.5 3.5 UsesKAM : Refractory, PorcelainKES-L, M, N Series High-density and high-strength alumina porcelain Industrial machine pads Special refractories Electronic parts Cutting tools Catalyst support Packaging Flexible Container Bag(1,000kg) Paper Bag(25kg)
