Thermophysical, Thermochemical Behavior of Cu Coated SiC Composite Particles

25SiC/75Cu (vol%) coated composite particles were prepared by the reduction-rotation precipitation process. The simultaneous DSC-TG-MS technique was used to characterize the thermophysical and thermochemical behaviour of the coated composite particles. The results show that a decomposition reaction occurs at about 846℃, releasing O2 and leading to a weight loss. The eutectics of Cu-Cu2O and Cu2O-SiO2 melts at about 896℃. SiC will react with Cu at above 950℃, resulting in the formation of CO2 and weight loss.
