Alumina Ball with High Crushing Strength

Alumina Ball with High Crushing Strength
The XINTAO 99High Alumina Support Media is in chemical composition99+% alpha alumina and amaximum 0.2wt% SiO2. Because of its highalumina content and low silica (SiO2), it's avery excellent and ideal product for high temperature and steam applications, such as secondary reformers in ammonia processing, where leached silica will coat downstream equipment or foul the catalyst bed.
The XINTAO 99High Alumina Support Media has very excellent thermal properties, with its high density high-temperature resistance 1550ºC, also it's agood choice for heat retention ordecelerationmedia.
For its superior chemical resistance, it's suitable for applications inole finprocesses, such as ethylene dryers, where there's the polymerization problem.Technical ParameterModelXT99 Alumina Ceramic BallColorWhiteShapeBallChemical compositionMin.%Max.%Usual %Al2O39999.699.3SiO2/0.20.18Fe2O3/0.20.02TiO2/0.550.02CaO/0.10.2MgO/0.10.05Na2O/0.250.1K2O/0.20.13Physical propertiesLeachable Iron (%)≤0.01Apparent Porosity by Weight (%)≤7.0H2Oabsorption (wt.%)<4.0Acid resistance (%)>99.8Alkaline resistance (%)≥90Bulk Density(g/cm3) 2.1(lb/ft3)131Specific density (kg/m3)3400(lb/ft3)212Moh's hardness (scale)>8.0Thermal conductivity (w/m2.k)0.7-0.8Max.
