Continuous Synthesis of Nanominerals in Supercritical Water

다국어 초록 (Multilingual Abstract)

The synthesis of minerals should play a crucial role in the development of new and advanced materials. Since 2016, a renewal of interest to enlarge the mineral synthesis towards industrial requirements has been observed, especially thanks to three main recent papers. The innovative process exposed combines a continuous process with the use of supercritical water. In addition to curtail synthesis times, this process offers a control on the particle characteristics (size, crystallinity, structure, etc.) and a capacity to be easily transferable at an industrial scale. This innovative concept is demonstrated with the synthesis of three minerals which are the talc (a phyllomineral), the xonotlite and the tobermorite (two inominerals). This article proposes an overview of the possibilities to synthesize nanominerals in continuous processing for the development of advanced materials with promising industrial applications.
Making minerals: This Concept article highlights a fast and continuous method to synthesize phyllo‐ and inominerals. In few tens of seconds, highly crystalline and synthetic nanosized talc, synthetic xonotlite or synthetic tobermorite are produced using this process. This article highlights a new, efficient and sustainable route towards the development of new advanced and functional materials.
