ceramic ball

ceramic ball is resistant to acid,alkali,salt and all organic solvents.Inert ceramic ball is used as a support and a covering material in reactors in oil refinery, chemical, fertilizer, natural gas and environmental protection industries, it can improve the distribution of gas & liquid and protect the catalyst from shocking by the rushing fluids.Technical data Type Feldspar Feldspar-Mullite Mullite Mullite-Corundum Corundum Item Chemical composition% Al2O3 20-30 30-45 45-70 70-90 90 Al2O3+SiO2 ≥90 Fe2O3 ≤ 1 Water absorption, % ≥5 Acid resistance , % ≥ 98 Alkali resistance,% ≥80 ≥82 ≥85 ≥90 ≥95 Thermal resistance, ≥1300 ≥1400 ≥1500 ≥1600 ≥1700 crushing strengh N/piece Φ3 ≥120 ≥140 ≥150 ≥160 ≥200 Φ6 ≥400 ≥420 ≥440 ≥480 ≥500 Φ8 ≥480 ≥520 ≥600 ≥620 ≥650 Φ10 ≥600 ≥700 ≥800 ≥900 ≥1000 Φ13 ≥1000 ≥1100 ≥1300 ≥1500 ≥1800 Φ16 ≥1500 ≥1600 ≥1800 ≥2300 ≥2600 Φ20 ≥1800 ≥2000 ≥2300 ≥2800 ≥3200 Φ25 ≥2500 ≥2800 ≥3200 ≥3600 ≥4000 Φ30 ≥3000 ≥3200 ≥3500 ≥4000 ≥4500 Φ38 ≥4000 ≥4500 ≥5000 ≥5500 ≥6000 Φ50 ≥6000 ≥;6500 ≥7000 ≥8500 ≥10000 Φ75 ≥10000 ≥11000 ≥12000 ≥14000 ≥15000 Bulk density, kg/m3 1300-1400 1400-1500 1500-1600 1600-1800 1800 Note: The data of bulk density is given for reference only, not as the acceptance criterion.
