Most likely, at the initial stage of microwave sintering, the actual temperature in the contact zones (necks) was much higher than the average temperature within the volume of the material.
The fabricating methods of CNTs/ceramic composites include hot pressing process (HP), hot isostatic pressing-sintering (Sinter-HIP), spark plasma sintering (SPS), microwave sintering, and high-temperature extrusion molding according to the sintering process [ 86, 87].
The La3+ and Co2+ substituted Sr1−xLaxFe12−xCoxO19 (x = 0 0.5) ferrites with Bi2O3 sintering aid were prepared by microwave sintering method at a low sintering temperature of 870 °C compatible with low temperature co-fired ceramics (LTCC) systems.
The sintering parameters including sintering temperature, sintering time, sintering atmosphere and sintering position were discussed.
Dense ceramics of cobalt ferrite were prepared by non-conventional, microwave sintering of synthesized nanopowders at temperatures of 850 900 °C.
Low-temperature sinterable microwave LiAlSiO4-based solid-state material was investigated with regard to microwave dielectric properties as functions of the sintering temperature.
The powder was densified at different temperatures using a microwave sintering method.
Compared to the traditional sintering method in resistance furnace in this work, the microwave sintering displayed distinct advantages, including shorter sintering time, lower sintering temperature, more homogeneous element diffusion, more excellent holding force between in diamond and alloyed matrix.
Microwave sintering shows a rapid densification at low temperatures for ferroelectric films on a metal substrate.
The microwave dielectric properties are found strongly correlated with the sintering temperature as well as the amount of V2O5 additions.
