In order to achieve an advanced pulsed-current-sintering (PCS) technique, this work was performed to understand the sintering mechanisms and to clarify the effect of the sintering parameters, such as heating rate, sintering temperature, dwelling time, loading schedule and so on, on PCS processing of MgAl2O4 spinel. It is found that the sintering behavior changes sensitively with the parameters and dense fine-grained ceramics can be fabricated by carefully optimizing the parameters. Loading at high temperatures, for example, can attain high density spinel even at a high heating rate of 100°C/min, and hence, can save the total processing time.

为了实现高级脉冲电流插入（PC）技术，进行了这项工作，以了解烧结机制并阐明烧结参数的影响，例如加热速率，烧结温度，住宅时间，加载时间表等，对MGAL2O4纺丝的PC处理。发现可以通过仔细优化参数来制造烧结行为对参数的敏感性变化，并且可以通过仔细优化参数来制造。例如，即使以100°C/min的高加热速率，在高温下的加载也可以达到高密度尖晶石，因此可以节省总处理时间。
