High alumina ceramic packing balls are spherical industrial media manufactured from alpha-alumina (α-Al₂O₃) with low silica content. They are classified by alumina (Al₂O₃) content into 90-series (≥90%), 92-series (≥92%), 95-series (≥95%), and 99-series (≥99%). These products serve as catalyst bed support and covering materials, as well as tower packings, in reactors and packed columns across the petroleum, chemical, fertilizer, natural gas, and environmental protection industries. Their primary functions include buffering the impact of incoming liquid and gas streams on catalysts, protecting vulnerable catalyst beds, and improving fluid distribution within the reactor. Key performance parameters vary by grade. For the 92-series, typical specifications include Al₂O₃ ≥92%, Fe₂O₃ ≤0.25%, water absorption ≤6%, and bulk density ≥3.0 g/cm³. The 95-series offers Al₂O₃ ≥95%, Fe₂O₃ ≤0.15%, water absorption ≤5%, and bulk density ≥3.1 g/cm³. Crush strength is diameter-dependent: a 3 mm (1/8"...

In industries where conveying abrasive materials is a daily operational reality, premature pipeline failure is not just a maintenance headache — it ’ s a direct hit to the bottom line. Our high-purity alumina wear-resistant ceramic pipes are engineered to solve this exact challenge. With an alumina (Al ₂ O ₃ ) content exceeding 95%, these pipes exhibit a Rockwell hardness of HRA 85-90, second only to diamond. This extreme hardness translates to exceptional resistance to sliding abrasion and particle impact, effectively extending service life by 5 to 10 times compared to traditional hardened steel pipes. Crucially, the exceptional hardness is matched by a low density of approximately 3.6 g/cm ³ , making the ceramic piping system significantly lighter than metallic alternatives, thereby reducing structural load and installation costs without sacrificing durability. The advanced manufacturing process is integral to the pipe ’ s superior performance. Each liner is formed through an isostat...

Wear-resistant alumina ceramic liner plates are specialty structural ceramic products manufactured from high-purity alumina (Al₂O₃) through dry pressing and high-temperature sintering at 1500–1700°C. The alumina content typically reaches no less than 92%, with 95% and above being standard grades. Typical technical specifications include: bulk density ≥3.6 g/cm³, Rockwell hardness ≥85 HRA, compressive strength ≥850 MPa, and fracture toughness KΙC ≥4.8 MPa·m¹/². The Mohs hardness reaches grade 9, second only to diamond. Product thickness ranges from 1.5 to 25 mm, customizable for various operating conditions. The material exhibits significantly superior wear resistance compared to metallic materials. Laboratory wear testing (p=76N, n=800 r/min, t=30min) shows wear loss ≤0.0002g. Under actual operating conditions, its wear resistance is 260–266 times that of manganese steel and 170–171.5 times that of high-chromium cast iron. With a density approximately half that of steel, it effectively...
