Microwave cured ceramics is a method that uses microwave heating technology to quickly solidify ceramic slurries. This method solves the problems of traditional thermal conduction heating methods such as slow heating speed, large temperature gradient, uneven curing and difficulty in preparing large-sized ceramic parts. Microwave cured ceramics have the advantages of good universality, simple operation, and high repeatability, and can effectively shorten the curing time of injection molding of large-sized ceramic parts and achieve continuous production.

Specifically, the process of microwave curing ceramics usually includes mixing ceramic powder, dispersant and deionized water to prepare a uniformly dispersed ceramic slurry, then adding a curing agent and mixing evenly, and degassing the slurry. Subsequently, the slurry with the curing agent added was injected into the non-porous mold and heated in a microwave heating device until the slurry solidified. After demoulding, the ceramic blank is obtained. After drying, the blank is placed in a sintering furnace for sintering, and finally a ceramic sintered part is obtained.

In the process of microwave solidification of ceramics, microwave heating is an internal heating method. The material heats itself rather than through heat conduction, so it has the characteristics of fast heating speed and high efficiency. At the same time, microwave heating can achieve uniform heating, so the ceramic material dries evenly during the microwave curing process. In addition, due to the selective heating characteristics of microwaves, more than 80% of the microwave energy is absorbed by water, further improving the heating efficiency.
