3M™ Silicon Nitride Materials and Components

3M™ Silicon Nitride is an extremely hard and corrosion-resistant ceramic material that is 60% lighter than steel. This material, Sintered Silicon nitride (Si₃N₄), is designed to offer a combination of excellent properties, including thermal and impact resistance, electrical insulation, and wear resistance. 3M™ Silicon Nitride offers a wide degree of design flexibility, making it an excellent alternative to stainless steel, superalloys, tungsten carbides, and first-generation ceramics such as Al₂0₃ and ZrO₂. These performance benefits make 3M™ Silicon Nitride an adaptable solution for applications in power generation, commercial vehicles, Electric Vehicles (EV), aerospace, chemical processing, oil & gas, and general industry.
