Alumina Ceramic Plate insulation board ceramic substrate
Alumina is the most commonly used technical ceramic material. Thanks to its very good electrical insulation, dielectric strength, and high-temperature resistance up to 1500 °C, Alumina Ceramic is ideal for electrical applications and high-temperature applications.
Alumina ceramics feature:
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.
• Network resistor,
• Chip resistor,
• Chip resistor array
• Thick-film hybrid IC
• Thin-film hybrid IC
• General isolator
