Unifore Pore Sizes 30um Aluminum Oxide Porous Ceramic Disc

Product Description

The porous ceramic disc is made of the orthopedic (alumina, silicon carbide, etc.)blended amount of binder, pore forming

agent,resist rare earth,after high temperaturesintering to different shapes,sizes.The strong, uniform porous ceramic has 40-50%

open porosity with a tortuous pore structure and is available in pore sizes ranging from 1 to 100 microns.
 

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.
