Nitride Bonded Silicon Carbide (NBSiC) plates are high-quality advanced refractory materials, manufactured with silicon carbide particles as the aggregate and silicon nitride as the bonding phase. Featuring exceptional high-temperature stability, superior mechanical strength, and excellent chemical corrosion resistance, this composite plate serves as a top-priority material for diverse high-demand industrial scenarios worldwide.
Core Advantages
NBSiC plates deliver outstanding performance in harsh working conditions where conventional materials fail easily.
Supports continuous operation at 1400°C and withstands peak temperatures up to 1750°C without deformation. Retains more than 80% of room-temperature strength at 1200°C, ensuring stable structural integrity for long-term service.
Thanks to the low thermal expansion coefficient, NBSiC plates resist cracking under repeated rapid heating and cooling cycles, making them perfectly suitable for intermittent kiln operations.
With a Mohs hardness of grade 9, they are three times harder than wear-resistant cast steel, greatly reducing material loss in high-friction working environments.
Chemically inert to acids, alkalis and molten metals, and possesses excellent thermal conductivity and electrical insulation properties for broad industrial compatibility.
Main Application Fields
NBSiC plates are widely used in various high-end industrial industries.
Commonly applied to blast furnace linings, cooling wall inserts and side walls of aluminum electrolytic cells, extending the service life of equipment to 10–15 years and effectively improving energy efficiency.
Acts as core kiln furniture materials for support plates, beams, kiln battens and other components, ensuring uniform heat distribution and helping produce high-quality finished products.
Used as anti-corrosion liners in the chemical industry and manufactured into wear-resistant parts for heavy machinery such as slurry pumps and cyclones.
For enterprises pursuing stable equipment operation, efficient production and cost reduction, nitride bonded silicon carbide plates stand out with superior performance and ultra-long service life. They are perfectly adaptable to all industrial working conditions requiring high temperature resistance, wear resistance and corrosion resistance, effectively reducing equipment replacement frequency and cutting production and operation costs.
