Abstract
Ion exchange from K0.8Zn0.4Ti1.6O4 to protonated compound while avoiding the dissolution of the Zn element succeeded was successful when NH4NO3 molten salt solvent was used. Based on FT-IR measurements and chemical analysis, it was thought that the ion-exchange compound changed to (NH4, H3O)0.87K0.03Zn0.35Ti1.6O4. Furthermore, the ion-exchange compound showed through chemical analysis data and x-ray diffraction data that the Zn element remained in the crystal structure at various sintering temperatures.
