| Abstract Scope |
Synthesis of non-oxide ceramics typically requires high temperature (> 1000 °C) and protective atmosphere – commonly argon or vacuum – to avoid the oxidation of the precursors. Furthermore, conventional synthesis routes typically entail a milling step to produce fine powders, increasing operating costs and introducing potential impurities. Nowadays, industry and society are demanding novel sustainable processes, where less energy is consumed and sustainable compounds are used. In this work, we will present a novel synthesis route for non-oxide ceramic powders, which is referenced as Molten Salt Shielded Synthesis or MS3. MS3 is carried out at lower temperatures than conventional synthesis routes, in air instead inert atmospheres, and does not require any milling step to obtain fine and loose powders. Synthesis of different ternary transition metal compounds (MAX phases such as Ti3SiC2, Ti2AlC and Cr2AlC) will be shown, as well as the possibility for other non-oxide ceramics such as TiC. |
