Spark plasma sintering mechanism of Al2O3-based ceramics granulation powder
In this paper, spark plasma sintering (SPS) was used for the first time to rapidly densify Al2O3-based granulated powders at different temperatures, and the sintering mechanism of SPS was analyzed. It is found that the optimum sintering temperature of ceramic materials is 1450 °C. Under the action o...

| description | In this paper, spark plasma sintering (SPS) was used for the first time to rapidly densify Al2O3-based granulated powders at different temperatures, and the sintering mechanism of SPS was analyzed. It is found that the optimum sintering temperature of ceramic materials is 1450 °C. Under the action of rapid heating rate (100 °C/min) spark sintering and strong electric field generated by low temperature and large current, the transport and migration of substances are accelerated, and the grains can grow effectively. The slip rearrangement between the particles caused by the discharge effect promotes the discharge of all the gases produced by the pyrolysis of organic matter, and finally the sintering densification degree of the material is optimized. |
