摘要

Potassium carbonate (K2CO3) and sodium carbonate (Na2CO3) are useful inorganic alkali salts with a multitude of uses, although both can be unstable at room temperature. The focus of this work was to react these two unary carbonates together to form KNaCO3 single crystals, and to determine the structure of the resulting crystals. The symmetry of the crystals was assigned to the monoclinic space group C2/c (No. 15), with lattice parameters (Ǻ) of 5.4546(7), 9.462(1), 6.1282(7), and β = 95.209(4). The K and Na are located on fully occupied, symmetry-unique atomic positions. The phase evolution of K2CO3 and Na2CO3 to form KNaCO3 was also examined using in situ high temperature X-ray diffraction. The final compound in both single crystal and powder form was found to be stable over time at room temperature.
