Comparing hydrothermal sintering and cold sintering process: Mechanisms, microstructure, kinetics and chemistry

“…Among other low temperature sintering techniques, Cool-SPS was used to densify thermodynamically fragile materials, including reactive sintering of hydrated precursors at temperatures below 400°C [28][29][30].…”

Enhancing Mechanical Properties of the Spark Plasma Sintered Inconel 718 Alloy by Controlling the Nano-Scale Precipitations

“…Spark plasma sintering (SPS), as a relatively new powder metallurgy (P/M) technique, is well-suited for the preparation of IN718 alloy due to its assurance of high fabrication efficiency, relative density, and compressive strength of the SPS IN718 material [15]. Compared with other P/M techniques, SPS is assisted by a highly-pulsed DC, which provides the heat directly inside the sample by the Joule effect [16]. With the simultaneous application of uniaxial pressure, the samples can be fabricated rapidly by SPS [17].…”

Cold sintering of diatomaceous earth

“…[11][12][13][14][15] The first materials produced by CSP were mainly salts and soluble compounds, 3,16 although several activities have been then carried out on ferroelectrics, [16][17][18] piezoelectrics, 19 magnetic ceramics, 20 semiconductors, [21][22][23] transparent ceramics, 24 bioceramics, 14 and ionic conductors. [25][26][27] More recent works regard water-assisted cold processing of silicate ceramics including cold sintering of quartz, 28 soda-lime silicate glass, 15 and quartz-PTFE composite 29 or cold joining of silica 30 and cold isotactic pressing of glass monoliths. 31 Although CSP is inspired by phenomena taking place in nature (like the formation of sedimentary rocks 32 ), no research activities regarding the application of CSP on nonsynthetic industrial minerals have been reported to the best of the authors' knowledge.…”
