Synthesis and Characterization of Cubic Zinc Titanate Doped with Lithium

摘要

Cubic (Zn,Li)TiO3 powders were synthesized through a modified sol-gel route including the Pechini process via a three-step heat treatment.The as-synthesized (Zn,Li)TiO3 could be stable up to 1000°C.The dielectric constant and dielectric loss tangent of all the synthesized (Zn,Li)TiO3 samples at different measurement frequencies showed the similar tendency.At the same frequency,the dielectric constant and the dielectric loss tangent of (Zn,Li)TiO3 samples decreased and increased,respectively,with the lithium doping content increase.The as-prepared (Zn,Li)TiO3 showed improved microwave dielectric properties,and its maximum value of quality factor could reach 34000 GHz.
