Formula: Si₃N₄
Form: Tube
Material: Reaction Bonded Silicon Nitride/Si3N4
Commodity: Ceramics
Inside Diameter:
5mm
Reaction Bonded Silicon Nitride/Si3N4 Tube is a tubular product manufactured by Goodfellow that is made of silicon nitride (Si3N4). Silicon nitride is known for its high strength and fracture toughness at high temperatures. This advanced ceramic material also has excellent thermal shock resistance. Reaction Bonded Silicon Nitride/Si3N4 Tube is available for use in applications that require tubes capable of withstanding very high temperatures, such as gas turbines, heat exchangers, and automotive engines. Goodfellow offers this tubular product in 2 sizes to suit different requirements.
