I am looking for literature about the microwave sintering especially for porcelain ceramics. Basically, I intend to use microwave and radiation heat as a hybrid sintering system for the particular material. But I just have got a few literature on this area.
So, please suggest me of either possibility/down-back or the controlled process parameter of this process.
Any suggestions would be really appreciated.
Warm regards,

The microwave heating runs only materials conducting electric current. The lower the conductivity of the material, the higher must be the frequency. Porcelain - insulator, so it starts to microwave heat up only by partial melting, that is, at a temperature above 1300 ° C. Thus, for sintering of the porcelain can not apply microwave heating. Sometimes using microwave heating for drying the molded ceramic articles. Such heating is possible, as long as there is water in the product. Once all the water evaporates induction heating stops by itself.
Dear Prof. Vadim Verlotski
From my previous research, I think porcelain can be couple with MW if it is heated above 400C (approx) and I pretty sure that the MW works well with the materials that behave dielectric properties not conductor.
Anyway, thank you for your valuable answer, I will find out more about this and will be updating on this question.
