Sintering is a critical processing technology in the production of ceramic materials that uses high heat to compact ceramic powders into a solid form. Sintering of pure oxide ceramics requires ...

Chao Shen, a graduate student on the team, said once the ceramic specimens are cooled, the dislocations improve the plasticity of ceramics at room temperature. “This method is more widely applicable ...

Traditionally, sintering HfC requires placing the raw materials in a furnace that can reach temperatures of at least 2,200 degrees Celsius -- a process that is time-consuming and energy intensive.

The cold sintering process (CSP) combines heat, pressure and the use of water to significantly reduce energy use as it lowers the temperatures required to produce ceramics to around 300 degrees ...

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 ...

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 ...

Multiphase composition design and entropy engineering control are promising strategies to improve the properties of ultra-high temperature ceramics (UHTCs). In this study, spark plasma sintering ...

Sintering, whereby the ceramic is heated to a high temperature to bond the particles of the powdered ceramic together, is probably the most commonly cited method.
