Abstract: Rapid sintering technique has been a hot topic for many years due to it’s advantages of saving extensive time and energy. In recent decades, rapid sintering techniques, such as spark plasma sintering, flash sintering, selective laser sintering, induction heating, microwave sintering and fast sintering with conventional sintering element, have been developed greatly and make the rapid sintering of advanced ceramic materials be possible. This article reviews the rapid sintering techniques and the sintering mechanisms during the fabrication of advanced ceramics over the past 20 years, and emphasizes on the effect of pulsed direct current and mechanical pressure on the microstructure, properties and sintering mechanisms during spark plasma sintering. This article also pointed out the development direction of rapid sintering techniques. On the one hand, it would be the further study of sintering mechanisms of rapid sintering techniques and the application of the sintering mechanisms to the industry production of advanced ceramics. One the other hand, to solve the problems of large scale and volume production in the industrialization of rapid sintering would be another development direction.
Key words: ceramics; rapid sintering; spark plasma sintering; sintering mechanism; flash sintering; induction heating
