High purity graphite is widely used as the sintering fixture material in the sintering industry. The graphite is high-temperature resistant and has a melting point higher than the sintering temperature. Under high temperature conditions, it does not infiltrate with glass and will not pollute glass. The graphite has sufficient mechanical strength and is easy to process.

The connector made by sealing glass and metal has good characteristics: 1. Good mechanical strength; 2. High temperature resistance; 3. Good sealing and corrosion resistance, suitable for harsh environment.

At present, the market is widely used in aerospace, automotive electronic connectors, sensors, 5g, integrated circuits and high-power devices.
