Product Description Alumina Al2o3 Porous Ceramic Disc for Vacuum Chuck is composed by the distributed evenly open pores which isinterconnected by shape likearch , when the fluid through these pores,the suspended matter, colloidal particles, organicmolecules are trapped, adsorbed inside the micropores,then track to achieve the purification and filtration homogenizingeffect.The porous ceramic has the advatage with high strength,wear resistance, high temperature, corrosion, pollution, porositydistribution, long service life and easy to regenerate, which is particularly suitable for a variety of gas, liquid filtration and fluidizedprocess.Main Application field:- New and refurbished alumina porous ceramic chucks for Disco, K & S, Applied materials TSK, Micro Automation, Load Point, etcdicing saws and grinders.- 4", 6", 8," 12″are regular sizes, And pore size include 15um, 30um, 50um, 100um.Materials are alumina (Color: white, light brown, dark brown, blue-gray).- Custom size (like square, oval shape, or irregular shapes) is available for us. Specifically tailored techniques include:? Spraying? Brushing? Backwashing? Oven firing? Dilute acid cleaning? Solvent cleaning plus steam? Ultrasonic cleaning Characteristics include: High flatness and parallelism Compact and uniform microstructure with high strength Good permeability and uniform adsorptionaffinity Long life time dressing easily. Applications? Used in tough applications to replace porous metal or as analternative to plastic or fabric media? Cleaned and reused using a variety of methods dependingon the contaminant to be removed? Filters for gases and liquids? Capillary Electrophoresis? Filtration for heavy metal ions (Cr, Ni etc) in water? High temperature chemical support for gas absorption? High efficiency flow through catalytic supports? Gas burners? Chromatography? Micro trapping systems and bio-catalytic supports? Vacuum holding plates (vacuum chunk)? Nano-membrane supports for sensor applications? Micro-bubble diffusers? Fine or micro channels for electrophoresis? Chemical or bio reactor The Detailed Regular Size as Below --- Regular size6, 8, 12 inchesDiameter Regular Tolerance+/-0.10 mmRegular Flatness+/-0.10 mmRegular Surface RoughnessRa 0.8-1.6Alumina (Al2O3)Pore SizeColor15 umLight Brown30 umBrown50 umBlue-Gray100 umBlue-GrayAlumina materials properties--- PropertiesUnitPore CeramicAl2O3 Contentwt%≥ 80SiO2 Contentwt%16-18Densityg /cm32.3-2.5Hardness (HRA)HRA ≥50Flexure strengthMPa ≥40Compressive StrengthMPa≥600Porosity Factor%40Work PressureMPa ≤10Acid Resistancemg/cm2 ≤10Alkali Resistancemg/cm2 ≤20
