An Experimental Study of the Formation of Talc through CaMg(CO3)2–SiO2–H2O Interaction at 100–200°C and Vapor-Saturation Pressures

<div>SEM micrographs and EDS analyses of the solid relicts in an FSCC containing dolomite and water after heating at 200°C for ~60 days. (a, b) Honeycomb-like talc; (c) dolomite grains with smooth edges and EDS result of talc (yellow arrow); (d) euhedral calcite formed in the relicts (white arrow) and cylindrical talc growing on the inner surface of the tube (yellow arrow).</div>
