Abstract:	The synthesis of layered K_0.81Li_0.27Ti_1.73O₄ from K₂CO₃,Li₂CO₃ and TiO₂ was studied. The results show that the layered K_0.81Li_0.27Ti_1.73O₄ could be synthesized from starting materials at a mixing ratio of n(K₂CO₃) ∶n(Li₂CO₃) ∶n(TiO₂)=(0.405~0.42) ∶(0.135~0.165) ∶1.73 at a reation temperature between 1 000 ℃ and 1 200 ℃, and longer reaction time and higher reaction temperature favour the formation of the product. At 1 200 ℃, Al2O3 which is the component of corundum crucible would react with the reagents to formK_0.81Li_0.27Ti_1.73O₄ impurity. So when the corundum crucible is used as the reaction container, the optimization reaction conditions are the reaction temperature is 1 100 ℃, the ratio of starting materials is n(K₂CO₃) ∶n(Li₂CO₃) ∶n(TiO₂)=0.405 ∶0.135 ∶1.73, and the reaction time is 24 h.
