Product Description Product Description Products Introduction of Mid-Alumina Ceramic BallMid -Alumina Inert ceramic balls are widely used in many fields, including petroleum, chemical engineering, fertilizer production, natural gas and environmental protection. They are used as covering and supporting materials of catalysts in reaction vessels and as packing in towers. They have stable chemical features and a low rate of water absorption, resist high temperatures and high pressure, and also resist the corrosion of acid, alkali and some other organic solvents. They can stand the change in temperature during the manufacturing process. The main role of inert ceramic balls is to increase the distribution spots of gas or liquid, and to support and protect the activating catalyst with low strength.Product Parameters Product ParametersChemical Composition of Mid-Alumina Ceramic BallAl2O3+SiO2Al2O3Fe2O3MgOK2O+Na2O +CaOOthers> 93%45-50%<1%<0.5%<4%<1%Physical Properties of Mid-Alumina Ceramic BallItemValueWater absorption (%)<2Bulk density (g/cm3)1.4-1.5Specific gravity (g/cm3)2.4-2.6Free volume (%)40Operation temp.(max) (oC)1200Moh's hardness (scale)>7Acid resistance (%)>99.6Alkali resistance (%)>85Crush Strength of Mid-Alumina Ceramic BallSizeCrush strengthKg/particleKN/particle1/8''(3mm)>35>0.351/4''(6mm)>60>0.603/8''(10mm)>85>0.851/2''(13mm)>185>1.853/4''(19mm)>487>4.871''(25mm)>850>8.51-1/2''(38mm)>1200>122''(50mm)>5600>56Size and Tolerance of Mid-Alumina Ceramic BallSize and tolerance (mm)Size3/6/99/1319/25/3850Tolerance± 1.0± 1.5± 2± 2.5 Packaging & Shipping Certifications
