FEASIBILITY OF CONTACT-LESS TEMPERATURE CONTROL BY MICROWAVE RADIOMETRY DURING SINTERING OF POWDERED SiC AND Al/SiC SAMPLES

摘要

Heat gradients or pulses are generated in the center of ceramic and metallic powdered samples and their transient thermal emission is collected using a radiometer working around 3.3 GHz The ability of contact-less microwave radiometry to detect inverse temperature profile is shown for SiC or metal-ceramic composite powders (Al/SiC).
