Silicon material has high melting point (1412 °C) and corrosion-endurance, can be used in high temperature areas. It has high transmission rate in infrared range with coating, also a good option for far infrared windows in detectors and sensors. Widely used in instrumental and military applications. It is also one of the valuable semiconductor materials.
