Application

Silicon aluminum oxynitride is designed to serve as a robust and versatile advanced ceramic material, combining remarkable properties of both silicon nitride and aluminum oxide. Its medium density and low Young's modulus, along with a low coefficient of linear thermal expansion, provide excellent thermal shock resistance and low thermal conductivity, making it ideal for high-temperature applications. It also demonstrates impressive mechanical strength, with a high flexural strength and outstanding fracture toughness and hardness. The material's fine microstructure, with under 1% open porosity, ensures durability and resilience in demanding environments. Additionally, its resistance to oxidation and corrosion from molten nonferrous metals, including aluminum, brass, and bronze, highlights its suitability for use in extreme conditions. Silicon aluminum oxynitride's unique blend of high-temperature strength, chemical inertness, and corrosion resistance makes it particularly useful in applications such as protection sheaths for immersion thermocouples, immersion heater and burner tubes, and various fixtures involved in nonferrous metallurgy and metal processing industries.
