TG-DSC-MS CHARACTERIZATION FOR THE ORGANIC ADDITIVE BURNOUT OF THE AQUEOUS TAPE CASTING ALUMINUM NITRIDE BY SELF-PROPAGATION HIGH TEMPERATURE SYNTHESIS METHOD

摘要

In this work, through the comparison analysis with the results of the Thermogravimetry-Differential Scanning Calorimetry-Mass Spectrometry (TG-DSC-MS) coupling techniques and XRD for the three organic additive and aqueous tape casting aluminum nitride in air and nitrogen, it can be found that the plasticity glycerol was almost burnout before 350 °C in two atmospheres; the binder (PVA124) was almost burnout before 600 °C in air, there was little left in nitrogen; The mass losses of the dispersant (DP270) before 600 °C in air and nitrogen were about 73.32% and 65.51%; The mass losses of the aqueous tape casting aluminum nitride before 600 °C in air and nitrogen were about 14.08% and 10.75%. The results showed that the burnout of the organic additive in the aqueous tape casting aluminum nitride in air was better than in nitrogen. The results of the XRD showed that there were no other phases except the AlN phase and Y2O3 phase. It can be concluded that the burnout of the organic additive in the aqueous tape casting aluminum nitride was complete. The thermal decomposition mechanism of burnout of the organic additive in the aqueous tape casting aluminum nitride is needed to study further.
