  • Comment: There is not yet enough notability to warrant an article. This is really just a single Science paper and a couple of patents. The other references are speculations on areas where it might be useful, not as yet proven. wP:TOO SOON for certain by some distance. Maybe in 3-5 years an article should be considered.

Ultrafast high-temperature sintering (UHS) is a method in which materials are synthesized from salt or oxide precursors via ultrafast, high-temperature sintering.[1] The UHS technique features a uniform temperature distribution, high heating (103 to 104 °C/min) and cooling rates (up to 104 °C/min), and high sintering temperatures (up to 3000 °C).[1] In a typical UHS process, the heating elements ramp up from room temperature to the sintering temperature in ~30 s or less, in which the temperature ramping stage is followed by ~10 s of isothermal sintering and then rapid cooling (in ~5 s) (a UHS image shown in Fig. 1). In this regard, UHS is distinct from conventional high-temperature syntheses that feature slow and near-equilibrium heating at limited temperature ranges (e.g., 1500 K for furnace heating)[2] for extended periods of time (typically hours) and generally slow heating and cooling (~10 K/min).

UHS utilizes high temperature to drive synthesis and sintering at extreme and non-equilibrium conditions. Additionally, the use of the ultra-high temperature can dramatically increase synthesis and sintering rates for rapid material production. The essence of UHS is the ability to precisely control the high temperature to ensure rapid sintering. Generally, the temperature, duration, and ramping rate can be independently controlled for specific synthesis and sintering requirements. As a result of these characteristics, UHS is particularly applicable for the general and rapid ceramic synthesis and sintering, novel post-sintering structures and materials producing, 3D printing ceramic precursors manufacturing,[3][4][5] in addition to well-defined interfaces between multilayer ceramic compounds.

Realization edit

The UHS method was invented by Dr. Liangbing Hu and his team at the University of Maryland, College Park. The technology is also patented.[6][7] The UHS was first realized by Joule heating of carbon materials to a high temperature with a short duration and rapid heating and quenching, which are controlled by electric power with a high temporal resolution.[1]

Since high-temperature heating is ubiquitously used for reactions and materials synthesis, innovative UHS processes have been discovered and demonstrated, enabling the rapid experimental validation of new material predictions from computation, which facilitates materials discovery spanning a wide range of compositions. Several applications may benefit from this methodology, including ceramic, alloys, high-temperature materials, thin-film SSEs and battery applications.[8][9] This technique is first published on Science as a Cover article.[1] The UHS rapid sintering is also listed as a R&D 100 winner.[10]
