Crystalline calcium carbonate was deposited on various substrates (substrate temperature of 80 °C) from a saturated calcium hydrogen carbonate solution (solution temperature of 10 °C). A single aragonite phase deposited on the Al substrate, whereas a mixed phase of aragonite and calcite grew on the soda lime glass, borosilicate glass, silica glass, and polycarbonate substrates. With increasing deposition time, the crystal size and the proportion of calcite on the soda lime silicate glass substrate increased. Furthermore, calcite crystals were preferentially deposited on an Al substrate with a thin film of Au as a buffer layer (Au/Al substrate).
