Abstract Flash sintering, renowned for its rapid densification of ceramic materials, lacks comprehensive studies on the influence electric field and current density due to potential variations based furnace type sample geometry. This study introduces a computational modeling technique using response surface methodology predict densification, onset temperature, steady-state temperature in flash sintering. A mathematical model was developed optimize 8YSZ cylindrical dog-bone samples, employing...
Processing of materials in the form ceramics normally involves several steps including calcination at a relatively low temperature for synthesis end-product powder and sintering high densification. The work we have been developing introduces novel approach enabling plus single running experiment by using electric fields, ending with dense that display grains noticeably finer than conventional processing. This new paradigm is fully illustrated experiments conducted on amorphous CaCu3Ti4O12...
Alumina porous ceramic with controlled pore size distribution was produced and its potential as a random laser host is investigated. Bi-chromatic observed from rhodamine B infiltrated when excited by 532 nm pulsed laser. Two regimes were characterized associated the excitation of monomers dimers. The results show that this class material very promising for development low-cost solid state lasers.

Abstract Reactive flash sintering (RFS) enables the simultaneous synthesis and of ceramics has been shown to affect reaction pathway different materials. Herein, in situ synchrotron X‐ray diffraction (XRD) is used investigate (Mg,Ni,Co,Cu,Zn)O entropy‐stabilized oxide formation during: (i) conventional heating (ii) RFS under current rate‐controlled mode. The same verified both instances: starting rock‐salt (RS), spinel (Co 3 O 4 ), tenorite (CuO), wurtzite (ZnO) phases transform into a...
We investigated the use of metallic silver as a catalyst for flash sintering on hydroxyapatite/zirconia (HZ) composites. Adding 3 wt.% to ceramic powder reduced onset temperature (from 1084 °C 925 °C) and also electric field 300 V.cm−1 150 V.cm−1) used in process. attribute this behaviour formation percolation path that acts heat source, accelerating thermal runaway. As result, both required were reduced. Furthermore, results suggest temperatures along paths are high enough reach boiling...
