Abstract
LiNiSi2O6 and LiTiSi2O6 spodumenes have been synthesized by solid state reaction at 60 kb and 1000-1300°C. Their cell dimensions were determined as follows: LiNiSi2O6 spodumene; a=9.423A, b=8.447A, c=5.251A, β=110.52°, and V=391.46A3, and LiTiSi2O6 spodumene; a=9.688A, b=8.797A, c=5.317A, β=108.99° and V=428.46A3. The present cell dimensions of the LiNiSi2O6 and LiTiSi2O6 spodumenes are compared with the published cell dimensions of six LiM3+Si2O6 spodumenes, and it is revealed that the cell dimensions of the LiM3+Si2O6 spodumenes show an almost smooth change with the octahedral ionic radii of the M3+ ions as two different trends; one is Al-Fe-Sc-In series and the other Ni-Cr-V-Ti series.
