Hot-Pressed Silicon Nitride Substrates

A hot-pressed silicon nitride ceramic (HPSN) substrate is a type of ceramic material made from silicon nitride (Si3N4) powder. It is produced by a process called hot pressing, where the powder is pressed under high temperature and pressure to form a dense, strong, and highly durable ceramic material. This process results in a ceramic substrate with excellent mechanical, electrical, and thermal properties, making it ideal for various applications in the electronics industry.

Silicon Nitride Substrate Manufacturer

At Great Ceramic Company, we leverage state-of-the-art hot-pressing capabilities to manufacture high performance silicon nitride (SiN) substrates.

Hot pressing allows us to fully densify the SiN powder at high temperatures under pressure. This optimizes the microstructure to achieve exceptional thermal conductivity up to 85 W/m·K.
