Protection against thermal radiation

Rectangular susceptor
Rectangular susceptor

Graphite Materials manufactures high-quality rectangular and cylindrical susceptors. These act as “heat shields” that protect against direct thermal radiation (hotspot). Susceptors, also known as muffles, absorb heat and emit it evenly across their own surface.

Susceptors by Graphite Materials are used when sintering hard metals and ceramics, as well as in complex heat-treatment processes.
