Abstract

A new processing method for solidifying calcium carbonate (CaCO₃) powder has been developed using hydrothermal hot-pressing technique. The solidification of calcium carbonate was achieved via vaterite/aragonite-calcite wet transformation under the conditions of the low temperature range of 50≈175°C within short period of below 4.0 h. The tensile strength of the solidified CaCO₃ body based on aragonite reached approximately 8.0 MPa. Moreover, the tensile strength of the body could be enhanced by the addition of Chitosan.
