Alumina Plate 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, ion implants, photolithography, and semiconductor parts.
• In traditional industries, alumina ceramics are ideal for products such as injector tubes, gas nozzles, and insulators.
