Effect of Temperature and KOH Concentration on Hydrothermal Synthesis of SrTiO3 Dendrites

Article Preview

Abstract:

SrTiO3 dendrites were successfully synthesized by hydrothermal method. An obvious morphology evolution from cubic-like shape to dendrite was observed when KOH concentration varied from 1M to 0.1M at 80°C. A decrease in KOH concentration was found to be favorable for the formation of dendrites. Star-like shape SrTiO3 crystals instead of dendrites were obtained when the temperature was lowed to 40°C.
