Dense and strong calcite ceramics prepared by room‐temperature cold sintering based on high‐pressure‐enhanced solubility

Dense and strong calcite (CaCO3) ceramics were prepared by room‐temperature cold sintering with the aid of water and high pressure of up to 900 MPa. Under atmospheric pressure, calcite is barely soluble in water. However, the microstructure evolution and stress‐strain analysis during cold sintering...
