■ Introduction: Silicon Nitride (Si3N4) ceramic is an excellent combination of material properties. They are nearly as light as silicon carbide (SiC), but their microstructure gives them excellent thermal shock resistance and their high fracture toughness makes them resistant to impacts and shocks. It is formed by cold isostatic pressing and sintered by Gas Pressure Sintering (GPS) and Hot Isostatic Pressure (HIP). Duratec is supplying various type of Silicon Nitride ceramic including Silicon Nitride insulating ring, Silicon Nitride thermocouple protection tube, Silicon Nitride insulation cover, Silicon Nitride sliding sleeve,Silicon Nitride Sheath,Silicon Nitride Degassing Rotor etc. ■ Specifications：
■ Features: • High strength good compactness • Low thermal expansion coefficient • Good corrosion resistance • Excellent thermal shock resistance
