Product detail
Silicon nitride ceramic, with the chemical formula Si3N4, is a highly versatile industrial ceramic material known for its exceptional performance. It boasts outstanding mechanical strength, fracture toughness, wear resistance, and thermal shock resistance, placing it at the forefront of industrial ceramics. Even at elevated temperatures, silicon nitride ceramics maintain impressive mechanical strength, with a maximum working temperature of 1200 ℃. Moreover, they exhibit remarkable resistance to infiltration and corrosion by various molten metals and alloys such as aluminum, lead, tin, silver, brass, and nickel.
The applications of silicon nitride ceramic are extensive, ranging from wear-resistant components to corrosion-resistant parts, capable of withstanding both room temperature and high-temperature environments. Furthermore, silicon nitride ceramic demonstrates excellent thermal stability, making it suitable for rapid heating and cooling processes.
Our silicon nitride rods are meticulously manufactured through isostatic molding and high-temperature sintering of superfine ceramic powders, resulting in fully dense rods with zero porosity. To meet the specific requirements of our customers, we offer precision machining, ensuring tight tolerances and polished surfaces. Whether you need prototype samples or batch production, we can produce ceramic rods with diameters ranging from 0.1mm to 300mm. Please feel free to contact us for any inquiries or orders related to silicon nitride rods; we are dedicated to providing comprehensive support.
