High-pressure synthesis of novel calcium carbides with polymeric carbon framework

This proposal aims to synthesize, study crystal structures and high-pressure behavior of calcium carbides employing single-crystal X-ray diffraction (SCXRD) in laser-heated diamond anvil cells (LHDACs). At first, we would like to establish the behavior field of known Ca-C phases. Second, we are going to perform a step-wise map of achievable PT conditions in order to explore the pressure and temperature effect on the formation of polyanionic carbon species in alkali metal-carbon systems. The bold goal of this proposal is to synthesize and quench novel polycarbides at ambient conditions.
