Description
In a previous series of experiments to decipher the number of existing ternary phases in K2O-CaO-SiO2 system, we proved the presence of K4CaSi6O15 as a stable compound at ambient conditions and solved its crystal structure. Recently, we further revealed that the compound undergoes two structural phase transitions with increasing temperature.Diffraction data collected between 462 K and 666 K show satellite reflections, which suggest that the phase is 3+2-dimensionally modulated.
