High-pressure synthesis of a 12CaO center dot 7Al(2)O(3)-12SrO center dot 7Al(2)O(3) solid solution
Solid solutions of 12CaO7Al(2)O(3) (C12A7) and 12SrO7Al(2)O(3) (S12A7) crystals were synthesized under high pressure. X-ray diffraction patterns revealed that the lattice constants of the synthesized samples depend linearly on the compositional ratio of C12A7 and S12A7. Electron-probe X-ray microanalyses show that the chemical compositions of the crystals are represented by xC12A7(1-x)S12A7 (0
