02 / MATERIAL & PROCESS
Silicon nitride bonded SiC radiant tubes
The material name describes both parts of the structure. Review the composition alongside the furnace duty, dimensions and acceptance criteria; the material name alone does not define the service limit.
- 01SiC aggregate + siliconMaterial composition and particle grading are part of the specification to discuss.
- 02Form the componentThe tube body and interfaces are defined by the part drawing and agreed dimensions.
- 03Nitride bondingDuring nitriding, silicon reacts with nitrogen to form the silicon nitride bond within the SiC structure.
- 04Confirm the specificationAgree the dimensions, property checks, acceptance criteria and documentation for the order.
03 / APPLICATIONS
Where it is used.
- 01Degassing-box heating, aluminium industryFor the heating systems of degassing boxes.
- 02Protecting SiC heating elementsAs protection tubes for SiC heating elements.
