Product Introduction

Our aluminum oxide plates (Al2O3) and porous alumina ceramic substrates are engineered for superior thermal management, electrical insulation, and chemical resistance. Ideal for heating elements, sensors, catalysts, and electronic packaging, our high-purity alumina ceramic plates deliver unmatched performance in extreme environments.

Industry Applications & Case Studies

1、Heating Elements & Thermocouple Insulation

Our alumina ceramic thin sheets are used in high-temperature heaters, providing uniform heat distribution and electrical isolation.

2、Catalyst Supports & Chemical Filtration

The controlled porosity of our aluminum oxide plates makes them ideal for catalytic converters and gas filtration.

3、Electronics & Sensors

Used as insulating substrates for thin-film sensors, power electronics, and RF components due to low dielectric loss.

4、Industrial Wear Protection

Alumina ceramic plates serve as abrasion-resistant liners in machinery, extending component lifespan.

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
