Results of these experiments are reported on figure 2 for two different die materials.
Effusivity of three die materials investigated in our lab are reported on table 1.
This concept requires also very high reflective insulating materials in the upper cavity and low effusivity die materials, like the in house patented Fiber Reinforced Refractory Castables.
