(Nanowerk Spotlight) Ceramics are an important class of materials with widespread applications in electronics and energy storage due to their high thermal, mechanical, and chemical stability.

With the aim to improve the thermal conductivity of yttria dispersed AlN ceramics through a short time and low temperature treatment under nitrogen atmosphere, millimeter wave (MMW) heating was ...

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 ...

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 ...

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 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 ...

We measure the sintering behavior of thin and thick films of ceramics made by stacking several layers of tapes. The stack thickness was varied from 0.12 to 0.50 mm. A powder pressed dog‐bone sample, ...

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 ...

Highlighting recent advancements in ceramic AM that are coming out of academic labs and are influencing the future of the ...

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, ...
