HYDROTHERMAL AND SOLID-STATE SYNTHESIS OF SODIUM ZIRCONIUM SILICOPHOSPHATES Academic Article uri icon

abstract

  • Nasicon has been prepared hydrothermally from zirconium phosphate, Zr(HPO4)2H2O, and Na4SiO4 in excess NaOH at 300C. If the excess NaOH is omitted a pre-cursor phase forms which on heating to 1200C yiels Nasicon. In its hydrated form Nasicon is hexagonal but on dehydration reverts to monoclinic. The triphosphate, NaZr2((PO4)3, is part of a solid solution system, Na1+4xZr2-x(PO4)3 with 1 > x > 0.12. This implies that the sodium zirconium silicophosphates may also exist in zirconium deficient form. 1981.
