“…Both microwave and plasma arc sintering hold forth the promise of rapid processing as well as refinements in microstructure and enhanced properties. Of course, the causes of enhancement in two techniques are unrelated [45]. Microwave sintering appears to be an attractive alternative to plasma arc sintering for large specimens, since the energy is deposited in the bulk of the material by dielectric loss mechanisms [45].…”

“…The first studies of the use of microwave radiation for high‐temperature processing of materials date back to 1960s . In the field of microwave sintering of ceramics, the pioneering experimental work was done by Tinga et al ., Berteaud and Badot, Meek et al ., and Lynn Johnson . By the end of 1980s, the feasibility of microwave sintering of oxide ceramic materials, such as Al 2 O 3 , ZrO 2 , Y 2 O 3 , has been demonstrated experimentally.…”

This paper reviews the basic physical notions underlying microwave sintering and the theoretical and numerical models of the microwave sintering process. The propagation and absorption of electromagnetic waves in materials, and the distribution of electromagnetic field in cavity resonators that serve as applicators for microwave processing are discussed and the electromagnetic modeling of such applicators is reviewed. The microwave absorption properties of ceramic and metal powder materials and the methods of their description are addressed. Self‐consistent electromagnetic and thermal models that are capable of predicting the temperature distribution in the microwave‐heated materials and dynamic effects such as thermal runaway instabilities are reviewed. The multiphysics simulations that combine electromagnetic, thermal, and sintering models and result in predicting densification, shrinkage, and grain structure evolution are discussed in detail. The significance of microwave nonthermal effects in sintering is demonstrated based on the experimental results, and the models of such effects are reviewed.

“…[15][16][17][18][19][20] In the SPS process, a pulsed direct current (dc) is applied to the sintering powder, and the activation of powder particles is thought to be achieved through the application of electrical discharges. The sintering mechanism of SPS can be found elsewhere in the literature.…”
