Overview of Silicon Nitride

Silicon Nitride (Si₃N₄) is a critical ceramic material renowned for its exceptional mechanical properties, high-temperature resistance, and chemical stability. It is widely used in the fabrication of high-temperature structural components, bearings, cutting tools, and electronic devices. Silicon Nitride can be prepared through methods such as reaction sintering or hot pressing, resulting in two crystalline forms: α-Si₃N₄ and β-Si₃N₄, depending on the production process.

Features of Silicon Nitride

High Hardness and Wear Resistance: Silicon Nitride boasts remarkable hardness and wear resistance, making it ideal for high-performance cutting tools.

Thermal Stability: It maintains excellent mechanical properties at extremely high temperatures, with a maximum usage temperature exceeding 1200°C.

Good Chemical Stability: It shows great resistance to corrosion by most molten metals and acid-base solutions.

Low Density: Compared to metal materials, Silicon Nitride has a lower density, beneficial for reducing the weight of structural components.

Excellent Electrical Insulation Properties: It is a preferred choice for electronic packaging materials.
