Lapped Polished Al2O3 Alumina Ceramic Wafer

Our lapped and polished alumina ceramic wafers represent the pinnacle of ceramic precision engineering, offering exceptional flatness, superior surface finishes, and outstanding material properties for demanding semiconductor, electronic, and optical applications. These ultra-pure Al₂O₃ substrates are manufactured to meet the most stringent requirements in industries where surface perfection and material consistency are critical.

Poduction process

1. Grind and crush the raw materials to be slurry or powder

2. se-different method to making the slurry or powder into semi-finished products

3. Put the semi-finished products into the kiln for dewaxing and sintering;

4. After forming and sintering, Ceramic Sleeves products can also be processed by subsequent CNC precision machining according to the drawing requirements. Then Q/C test.

5. Finally package Ceramic Sleeves by bubble paper or cartons and place it on tray for delivery
