Ternary switchable phase transition of CaCO3 by shock waves

Abstract : In the present article, we disclose shock wave induced crystallographic switchable phase transition of calcium carbonate nano particles (CaCO3 NPs). The observed profiles of powder X-ray diffraction reveal that CaCO3 NPs undergoes phase transitions in the sequential order from Calcite-I to Calcite-II and Calcite-II to Calcite-III at 50 and 100 shocks, respectively. Interestingly, reversible phase transitions have been observed from Calcite-III to Calcite-II and Calcite-II to Calcite-I at 150 and 200 shocked conditions, respectively. Rotational order-disorder of oxy-anions (CO3) and displacement of cation (Ca) take place because of the impact of shock waves thereby the observed ternary switchable phase transition results paving the way for the design of new multifunctional materials.
