Product Description

Alumina Al2o3 Porous Ceramic Disc for Vacuum Chuck is composed by the distributed evenly open pores which is

interconnected by shape likearch , when the fluid through these pores,the suspended matter, colloidal particles, organic

molecules are trapped, adsorbed inside the micropores,then track to achieve the purification and filtration homogenizing

effect.The porous ceramic has the advatage with high strength,wear resistance, high temperature, corrosion, pollution, porosity

distribution, long service life and easy to regenerate, which is particularly suitable for a variety of gas, liquid filtration and fluidized

process.

Main Application field:

- New and refurbished alumina porous ceramic chucks for Disco, K & S, Applied materials TSK, Micro Automation, Load Point, etc

dicing 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 adsorption

affinity Long life time dressing easily.

 

Applications

• Used in tough applications to replace porous metal or as an

alternative to plastic or fabric media

• Cleaned and reused using a variety of methods depending

on 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
