Sintering of Industrial Mullites in the Presence of Magnesia as a Sintering Aid
Journal of the American Ceramic Society, 2000The sinterability of two industrial mullite powders, in the presence of MgO as a sintering aid, was investigated. A glassy phase, which was generated during preparation, was present in both powders; this glassy phase had a strong influence on sintering, depending on its content, composition, and spatial distribution.

Master Sintering Curve: A Practical Approach to Sintering
Journal of the American Ceramic Society, 1996One of the ultimate objectives for sintering studies is to be able to predict densiflcation results under different thermal histories for a given processing method. It has been reported that the geometric parameters related to sintering often are functions only of density for a given powder and green‐body process, provided that one diffusion mechanism ...

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.

Mechanical Behavior of Non Sintered and Sintered Steel Wool
Advanced Materials Research, 2008Entangled materials are similar to cellular materials, with regard to their low density and discrete architecture. In this work steel wool (sintered in a furnace for various time at two temperatures) and non sintered steel wool are investigated. Experimental mechanical compression tests were performed on both materials.

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 ...

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.

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 ...

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
