Abstract: | A new compound in the system K2O:Li2O:TiO2 corresponding to the formula was found to be orthorhombic with a=3.821, b=15.921, c=2.973A space group Cmcm. The similarity between this unit cell and those of RbxMnxTi2?xO4 and FeO(OH) has been used to predict the structure of this new phase. From the composition of this phase and that of the hollandite and ramsdellite phases in this system, it can be deduced that some of the Li+ ions occur in the tunnels as well as in octahedral coordination substituting for titanium. |
