Reaction Bonded Silicon Nitride/Si3N4 Rod
Reaction Bonded Silicon Nitride/Si3N4 Rods are part of our wide range of ceramic materials. They are made by nitriding compacted silicon powder, leaving a small amount of unreacted silicon to aid densification. These rods combine high strength, toughness and thermal shock resistance. These properties make them suitable for applications like mechanical seals, bearings, nozzles and crucibles operating at high temperatures. We offer 3 variations of Reaction Bonded Silicon Nitride/Si3N4 Rods to meet your specific requirements.
