Sol–Gel Synthesis of a Zn-Doped Lithium Tantalate Growth Charge

  • Published:
Inorganic Materials Aims and scope

Abstract—

We have developed a method for the synthesis of a zinc-doped lithium tantalate (LiTaO3) growth charge using high-purity tantalum-containing solutions, which is based on the heat treatment of lithium-, tantalum-, and zinc-containing citrate precursors. The thermolysis products have been characterized by thermal analysis, X-ray diffraction, and infrared absorption spectroscopy. We have optimized synthesis conditions and zinc concentration for obtaining a single-phase LiTaO3〈Zn〉 growth charge. Using the proposed process, we have obtained LiTaO3〈Zn〉 materials with tailored dopant concentrations, which can be used in both LiTaO3〈Zn〉 crystal growth and the preparation of doped lithium tantalate-based functional ceramics.
