Microwave sintering (MW) allows fast heating (?30 min) and densification of ceramic materials, like alumina Al2O3. In order to predict the final material properties (density, size grain size) mechanical SOVS (Skorohold Olevsky Viscous Sintering) model is adapted validated for conventional alumina. The implemented on ABAQUS with UMAT subroutine. Secondly, modified microwave by adapting shear vis...

A novel NaAgMoO4 material with spinel-like structure was synthesized by using the solid state reaction method and the ceramic sample was well densified at an extreme low sintering temperature about 400°C. Rietveld refinement of the crystal structure was performed using FULLPROF program and the cell parameters are a = b = c = 9.22039 Å with a space group F D -3 M (227). High performance microwav...

A unit cell based numerical approach to model the metal powders and metal-dielectric composites at microwave frequencies is proposed. The unit cell based numerical modeling helps to compute the equivalent reflection and transmission coefficients of these materials, which are commonly used measured parameters at RF and microwave frequencies. The computation of the reflection and transmission coe...
