Densification and Sintering Kinetics in Sintered Silicon Nitride
Journal of the American Ceramic Society, 1992The sintering sequence of Y2O3‐Al2O3‐doped Si3N4 was investigated with respect to the relationship between densification, α→β transformation, and microstructural development. Quenching studies were performed to reveal these interactions during a complete sintering cycle.

Sintering and Densification (II)—New Sintering Technologies
2015Besides the conventional sintering techniques discussed in the previous chapter, various new sintering methods, such as microwave (MW) sintering, spark plasma sintering (SPS), and flash sintering, have been developed for ceramic processing. These methods have also been used to fabricate transparent ceramics.

Publisher Summary Sintering is a process of densification driven by interfacial energy. Material moves by viscous flow or diffusion in such a way as to eliminate porosity and thereby reduce the solid-vapor inter facial area. In gels, that area is enormous, so the driving force is great enough to produce sintering at exceptionally low temperatures ...

Journal of Magnetism and Magnetic Materials, 1976
Abstract A limiting density was reached at each sintering temperature. It was difficult to fix the operating mechanism during the initial stage of sintering. More than one mechanism overlap. At low temperatures surface diffusion predominates and at higher temperatures or firing periods a shift occurs to volume, then to grain boundary diffusion ...

Sintering and Densification (I)—Conventional Sintering Technologies
2015It is well known that, to produce ceramics, green bodies must be sintered at a certain high temperature for a given time duration to develop required microstructure and thus desired properties. In particular, transparent ceramics must be fully dense to achieve maximum optical transmittance. Sintering process is governed by a number of parameters, which

Field-assisted sintering: flash sintering
2020Flash sintering is a novel technique used for ceramics densification by means of heating and applying an electric field. Its advantages over conventional sintering have been discussed in the present work, amongst which, the following advantages are displayed: energy savings, shorter sintering times and preparation of ceramic materials with complex ...
