Large-diameter aluminum nitride ceramic sheets are precision AlN ceramic plates mainly used in semiconductor equipment and thermal control systems. Made from high-purity aluminum nitride, they combine high thermal conductivity with reliable electrical insulation. These sheets help manage heat, maintain insulation, and improve dimensional stability in wafer processing, power modules, laser systems, and other demanding electronic applications.
Aluminum nitride ceramic is selected when a component needs both efficient heat dissipation and electrical insulation. Compared with many common technical ceramics, AlN provides better thermal conductivity while keeping good mechanical stability and insulation performance.
