While the method of flash sintering can reduce the temperatures and time required to process ceramics in comparison with traditional methods, the technique often ...

In an exciting development for the field of aerospace engineering, the lightweight materials of airplanes and rockets might soon be getting stronger. A new method for making ceramic materials — which ...

ZnO varistor ceramics were synthesised by cold sintering/spark plasma sintering and post-annealing treatment. Intriguingly, the ZnO varistor ceramics present ultrahigh potential gradient, high ...

Porous α-Al 2 O 3 ceramics are widely used in various applications, including filters, substrates, and biomedical materials. These ceramics can be prepared using several methods, such as partial ...

In this study, the layered anisotropic structure of β-Li₂TiO₃ enables preferential dislocation slip under high pressure, amplified by nanoscale stress concentration, driving plastic deformation to ...

Professor Ian Reaney and researchers from the Department of Materials Science and Engineering at the University of Sheffield and Pennsylvania State University have released a new paper. This paper has ...

Ordinarily, when ceramic items are manufactured, the raw material has to be fired in a kiln at temperatures exceeding 1,000 ºC (1,832 ºF). Needless to say, it's a very energy-intensive process. Now, ...

Dense ceramic materials can form in nature under mild temperatures in water. By contrast, man-made ceramics often require sintering temperatures in excess of 1,400 °C for densification. Chemical ...

Engineers at Purdue University are using flash sintering to improve the plasticity of ceramics, an advance that could allow ceramics to sustain heavy loads and high temperatures without experiencing ...
