Product Introduction

Technical Ceramic Disc Alumina Products Ceramic Disk

Alumina wafer, made from aluminium oxide (Al2O3), is a key material in advanced ceramics. It is valued for its high electrical insulation, mechanical strength, corrosion resistance, and wear resistance. These properties make it suitable for a variety of industrial applications, including electronics, where it's used for its insulation properties, and in machinery parts for its strength and durability. Alumina wafers are also known for their high heat resistance, thermal conductivity, and hardness. With advancements, high-purity alumina (up to 99.96%) is now available, offering improved performance in demanding applications. This high purity level results in extremely high hardness, flexural strength, and dielectric strength, making alumina wafers ideal for applications requiring superior mechanical, thermal, and electrical properties.

Production 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
