Alumina plates are flat, rectangular-shaped structures made of alumina ceramic material, also known as aluminum oxide (Al2O3). Alumina is a highly durable and heat-resistant material that is widely used in various industrial applications, such as electrical insulation, refractory lining, and high-temperature processing.
Alumina plates are typically produced through a process of shaping and sintering of alumina powder, resulting in a dense and uniform ceramic structure. They can vary in size, thickness, and surface finish depending on the intended use and application.
Alumina plates have excellent mechanical and electrical properties, including high strength, hardness, and thermal conductivity. They are also resistant to chemical corrosion, making them suitable for use in harsh and corrosive environments.
Alumina plates are commonly used as a substrate for thin film deposition, such as in the production of electronic components like integrated circuits and solar cells. They are also used as a base for machining and drilling operations, and as a heat sink for high-temperature applications.

Alumina Plate Applications
Aluminum oxide ceramic plates have a wide variety of applications:
• Alumina plates are hard enough to become armor for personnel or vehicles.
• The corrosion resistivity of alumina plates makes them a great material for the chemical industry.
• Used as a material for industrial furnaces due to its ability to maintain its hardness at high temperatures.
• Used for making parts for CVD thin films, ion implants, photolithography, and semiconductor parts.
• In traditional industries, alumina ceramics are ideal for products such as injector tubes, gas nozzles, and insulators.
We handle our products with care to ensure they remain in their original condition during storage and transportation and to preserve their quality.
