Effect of composition on the enhanced microwave sintering of alumina-based ceramic composites

Microwave sintering of 8mol% yttria–zirconia (8YZ): An inert matrix material for nuclear fuel applications

“…Numerous reports have been cited in the literature on the advantages of MHH over conventional heating [13][14][15][16][17][18][19]. For instance, Janney et al [13] reported a 100-150°C reduction in sintering temperatures.…”

Microstructure of alumina produced by millimeter-wave heating

“…The frequency of MM radiation is over 30 GHz (<10 mm), but in this paper, a frequency of 28 GHz is also included. MM heating and ordinary microwave heating (at 2.45 GHz) have been compared in the case of alumina or alumina-zirconia ceramics [4,5]. The results have shown that MM heating resulted in higher densification at lower temperatures.…”

Sintering and electrical properties of Ce 1 − x Bi x O 2 − δ solid solution

“…In addition to shorter processing times, microwave sintering results in ceramics with improved microstructure and mechanical properties. The most intriguing effects observed during MW sintering are the higher densification [22][23][24] and reaction rates [25] when compared to conventional sintering. The reasons for higher densification rates have been attributed to lower activation energy for MW sintering [22,23].…”

During microwave heating, electrical energy from the microwaves is converted into heat.…”
